This is a Assertion and Reason Type  as classified in NCERT Exemplar

Correct Option: (i)

Ans: (i) Conductivity is due to the movement of ions. The number of ions present per unit volume decides the conductivity. It decreases on dilution. The number of ions per unit volume decreases on dilution. So, the assertion is correct, the reason is correct and the reason is the correct explanation of the assertion. Therefore, this option is correct

(ii) Assertion is correct, the reason is correct and the reason is the correct explanation of assertion. Therefore, this option is incorrect

(iii) Assertion and true both are correct therefore this option is incorrect

(iv) Assertion is true and the reason is false therefore this option is incorrect

(v) Assertion is true therefore this option is incorrect.

The admission process for International Institute of Technology and Management comprises different rounds. Students are admitted based on their candidature and performance in the selection rounds. The in-detailed steps for International Institute of Technology and Management admission process are as follows:

1. Application Process: The application process is conducted in both online and offline modes. Candidates can visit the college's website or the campus to apply for their desired programme.
2. Selection Rounds: International Institute of Technology and Management admissions are both merit-based and entrance-based. For courses such as MBA, BTech, BBA and BCA, students must qualify for the relevant national-level entrance exams. However, for the remaining courses, admissions are merit-based.
3. Final Admission: At last, the finalised students must pay a certain amount of the course fee and submit their documents for verification to confirm their seats.

Ans: Correct Option: (iii)

(i)A chemical reaction is spontaneous when the Gibbs free energy is negative. This is possible when E_cell is positive. E_cathode < E_{annode .}Therefore, the assertion is correct and the reason is incorrect and the reason is not a correct explanation of assertion. Therefore, this option is incorrect

(ii) E_cathode < E_annode  reaction is spontaneous when the Gibbs free energy is negative. This is possible when E_cell is positive. E_cathode < E_annode  . Therefore, the assertion is correct and the reason is incorrect. Therefore, this option is correct

(iv) Assertion is true and the reason is false therefore this option is incorrect

(v) Assertion is true therefore this option is incorrect.

This is a Assertion and Reason Type  as classified in NCERT Exemplar

Ans: Correct Option: (iii)

  (i)The electrode potential of Cu²⁺/Cu is negative. The electrode potential of 2H⁺/H² is 0.00V. Therefore, the assertion is correct and the reason is incorrect and the reason is not a correct explanation of assertion. Therefore, this option is incorrect

(ii) E $°$ Cu²⁺/Cu  is not negative so the reason is incorrect. Therefore, this option is incorrect

(iii) The electrode potential of Cu²⁺/Cu is negative. The electrode potential of 2H⁺/H² is 0.00V. Therefore, the assertion is correct and the reason is incorrect. Therefore, this option is correct

(iv) Assertion is true and the reason is false therefore this option is incorrect

(v)Assertion is true therefore this option is incorrect.

This is a Matching Type Question as classified in NCERT Exemplar

(i)- (b) ; (ii)- (a) ; (iii)- (d); (iv)- (c)

 The rate rule was discovered experimentally and can be used to predict the reaction rate and reactant concentrations.

The rate constant is the proportionality constant that describes the relationship between the molar concentration of the reactants and the rate of a chemical reaction.

The rate constant (k) of a reaction is proportional to its temperature, i.e., for a given reaction at a given temperature, the rate constant (k) is constant.

The order of a reaction is a quantity that has been empirically determined. As a result, the reaction rate is mostly determined by the slowest phase of the reaction. In the event of a complicated reaction, the stoichiometric coefficients of this rate-determining step match to the reaction order.

Ans:   (i) F₂ is a non-metal which is the best oxidizing agent since the standard reduction potential of F₂ is 2.87V.

(ii)Liis a metal and the strongest reducing agent because the standard reduction potential of Li is −3.05V.

(iii)Au³⁺ is a metal ion which is an oxidizing agent as standard reduction potential of Au³⁺ is 1.40V.

(iv) Br⁻is an anion that can be oxidized by Au³⁺ as standard reduction potential of Au³⁺ is 1.40V which is more than that of Br⁻ which is E $\mathit{Q}$ _Br2/Br−0=1.09V.

(v)Auis an unreactive metal

(vi)Li⁺ is a metal ion having the least value of standard reduction potential of 3.05V. Hence it is the weakest oxidizing agent

(vii)F⁻is an anion that is the weakest reducing agent as it has less oxidation potential.

Hence, the answer is:

(i)-c; (ii)-a; (iii)-g; (iv)-e; (v)-d; (vi)-b; (vii)-f

A catalyst can influence the rate of a process by lowering the activation energy

When it comes to molecularity, there can't be a fraction or a zero.

The second half life of a first order reaction is the same as the first.

Activation energy refers to the percentage of molecules with an energy equal to or greater than activation energy.

Correct orientation is not always present when it comes to energetically favourable activities.

Because the area under the Maxwell Boltzmann curve is constant, the total probability is one.
