For $\displaystyle \mathrm{A}_2+\mathrm{B}_2 \rightleftharpoons 2 \mathrm{AB}$
$\displaystyle E_a$ for forward and backward reaction are $\displaystyle 180$ and $\displaystyle 200 \mathrm{~kJ} \mathrm{~mol}^{-1}$ respectively If catalyst lowers $\displaystyle \mathrm{E}_{\mathrm{a}}$ for both reaction by $\displaystyle 100 \mathrm{~kJ} \mathrm{~mol}^{-1}$.
Which of the following statement is correct?
Official answer
From NTA’s final answer key for this paper.
(3)
