$A\left(g\right)?2B\left(g\right).$

$E_m\frac{2mol}{V\mathcal{l}}\frac{4mol}{V\mathcal{l}}$

$New{E_q}^m\frac{4-x}{V}\frac{4+2x}{V}$

$V\times 2\frac{4-x}{2V}\frac{4-2x}{2V}$

New Eqm $\frac{4-x-y}{2V}\frac{4+2x+2y}{2V}$

= $\frac{4-Z}{2V}=\frac{4+2Z}{2V}\left(Z=x+y\right)$

Now, KC = $\frac{{}^{}}{}$ $\frac{{\left[B\right]}^2}{\left[A\right]}=$ constant

$or,\frac{{\left(\frac{4}{V}\right)}^2}{\left(\frac{2}{V}\right)}=\frac{\left(\frac{4+2Z}{2V}\right)}{\left(\frac{4-Z}{2V}\right)}\Rightarrow Z=1.29$

 mole of B at new Eqm = 4 + 2Z = 6.58

Sucrose D (+) glucose + D (-) Fructose

  $\left[\alpha \right]=+66.5°\left[\alpha \right]=+52.5°\left[\alpha \right]=-92.8°$

Thus rotation changes from positive to negative after hydrolysis. Due to this reason hydrolysis of sucrose is known as inversion and mixture after hydrolysis is known as invert sugar.

Therefore option (B) is correct.

There is no ideal time to start the GATE preparation. Start early (from the first year itself). It is mainly because your bachelor's topics and chapters have the most weightage in the GATE question paper. The topics that are taught in your third year are the backbone. If you are clear with the fundamentals and concepts (taught in classes), then you do not require extra time to prepare for GATE. Just revise and practice questions. That's enough. 

So, start preparing for GATE right from the first year. Your brain is fresh with the concepts and formulas, thus making it easy to solve the questions and prepare for the exam. 

$\left[Zn{(gly)}_2\right]$ is optically active compound

Admission through COMEDK UGET is done through the COMEDK counselling based on the candidate's merit in the exam.

In H₂O (polar solvent) dibromophenol derivative and in CS₂ (non-polar solvent moneobromo phenol derivate is obtained.

^{$$ $Z=\frac{P{V}_m}{RT}\Rightarrow 0.5=\frac{24\times V_m}{24}$}

^{$V_m=0.5\mathcal{l}/mole$}

^{$\left(P+\frac{a}{V_m^2}\right)\left(V_m-b\right)=RT$}

^{$\left(24+\frac{a}{0.5^2}\right)\left(0.5-0.1\right)=24$}

^{$24+\frac{a}{0.5^2}=60$}

^{$\frac{a}{0.5^2}=36$}

^{$a=36\times 0.5^2=9\frac{atm-{\mathcal{l}}^2}{mo{l}^2}$}
 

The COMEDK UGET reporting time is different for each shift. The morning shift reporting time is 7:30 AM, for the afternoon shift timing is 12 PM, while for evening shift it is 4:30 PM.

The blue color of the solution is due to the ammoniated electron which absorbs energy in infrared region of light

There is no re-test for COMEDK UGET exam. Candidates who applied for the exam must report to their allotted exam centres as per their reporting time to appear for the test.

To prepare for the GATE General Aptitude section, here are some of the best books -

• Quantitative Aptitude for all competitive exams by Abhijit Guha
• A Modern Approach to Verbal and Non-Verbal Reasoning by R.S Agarwal

To fetch full marks in GATE General Aptitude, here's what you can do -

• Study English Grammar Textbooks.
• Try solving language puzzles and take online quizzes to test your skills and accuracy.
• Practice general aptitude section from previous year's GATE question paper.

Therefore option (b) is correct.

Candidates can pay the COMEDK UGET application fee in online mode only. The acceptable modes of payment are Debit/Credit cards, Netbanking or UPI.

$i=\frac{m_{theor}}{m_{app}}=\frac{30}{m_{app}}$

$\Delta T_b=i{k}_b.m]\underset{m-x}{\overset{m}{HA}}=\underset{x}{\overset{-}{H^{+}}}+\underset{x}{\overset{-}{A^{-}}}$

$0.0156=\left(\frac{m\times x}{m}\right)\times 0.52\times m$

m + x = 0.03

$\Rightarrow x=0.01\to i=1.5=\frac{30}{m_{app}}\Rightarrow m_{appp}=20$

The COMEDK UGET exam is conducted as a computer based test at designated test centres across the country.

Yes, GATE General Aptitude is common for all papers. The general aptitude section carries 15 marks out 100 marks, comprising 10 questions in total. The section mainly tests candidates' analytical and thinking skills in the exam. Here's a breakdown of the GATE General breakdown of questions -

• The GA section includes 5 questions of 1 mark and 
• 5 questions of 2 marks. 

The GATE marking scheme is the same for all.
