Ans: The cell reaction of a lead storage battery is as follows;

Pb + PbO₂ + 2H₂SO₄→2H₂SO₄ + 2H₂O

The density of electrolytes changes because water is formed and sulphuric acid is consumed as a product during discharge of the battery

The LLB programme at Faculty of Law, MIT-WPU has a total of 60 seats available. As admission is limited, it's essential for interested candidates to meet the eligibility criteria and perform well in the required entrance exams.

The chance of more than three molecules meeting at the same time is extremely minimal, reactions with molecularity more than three are extremely rare. Simultaneous collisions decrease as the number grows, the probability is very low, and more than three reactions with molecularity are uncommon.

Ans: Primary batteries contain a limited amount of reactants and once consumed are discharged. Secondary batteries take a long time to recharge. Fuel cells run continuously as long as reactants are supplied to them and products are consumed

With the combination of two different halogens, the interhalogen compounds are formed. When compared with pure diatomic halogen molecules, they are more reactive because the bond between different halogens are more polar and weaker. During reactions, it makes them more susceptible to bond cleavage.

Ans: The reactions taking place in the Daniel cell is as follows;

Zn⁺ + Cu²⁺ → Zn²⁺ + Cu

The number of electrons involved in two. The Nernst equation is as follows;

E_{cell =} E $°$ _cell - $\frac{-0.059}{2}$  log $\frac{\left[Z{n^2}^{+}\right]}{\left[C{u^2}^{+}\right]}$

From the above equation, we conclude that increasing the concentration of Zn^2+, E_cell will decrease.

Ans: The given cell reaction consists of two half cell reactions represented below as follows;

At anode: Cu→Cu²⁺+ 2e⁻

At cathode: Cl² + 2e⁻ →2Cl⁻

Here oxidation of copper and reduction of chlorine is taking place

The energy possessed by the reacting species increases as the temperature rises, the pace of a reaction increases. This raises the temperature and raises the average kinetic energy of the reactant molecules

This is a Short Answer Type Questions as classified in NCERT Exemplar

Ans: Standard hydrogen electrode (SHE) is used as a reference electrode and its electrode potential is assumed to be zero. The electrode potential of other electrodes is measured concerning standard hydrogen electrodes.

Due to their high electronegativity, small atomic size, greater ability to form multiple bonds, and absence of d-orbitals, the first elements of each group behave differently.

The reaction's activation energy is relatively high at room temperature and not readily available, the reaction is highly viable. H₂ (g) and O₂ (g)bond break and clash, allowing particles to pass across the energy barrier.

2H₂ + O₂→2H₂O

Because of the large activation energy, the water molecule does not form in this equation.

Ans: Conductivity due to the total number of ions present in the solution is termed as specific conductivity. An increase in the number of ions per unit volume increases. In addition to water, the number of ions per unit volume decreases therefore conductivity decreases.

Jamia Millia Islamia cutoff 2025 has been released across multiple specialisations. Based on Round 1 seat allotment results, BTech cutoff rank stood between 43789 and 256264 for General AII India category students. So, considering Round 1 cutoff, students seeking admission to UNIRAJ must secure over and above cutoff rank 43789 under unreserved quota.

Ans: pH of the substance depends on the concentration of hydronium ions present. Here the concentration of hydronium ions remains constant so pH remains constant.

The electrolysis reaction is as follows;

At anode: 2H₂O (l)→O₂ (g)+ 4H⁺ + 4e−

At cathode:4H⁺ + 4e⁻ →2H₂
