JEE Main 2020 — Chemical Equilibrium Question with Solution
From: JEE Main 2020 (Online) 5th September Morning Slot
Question
Consider the following reaction:
N2O4(g) ⇌ 2NO2(g); Ho = +58 kJ
For each of the following cases (a, b), the direction in which the equilibrium shifts is :
(a) Temperature is decreased.
(b) Pressure is increased by adding N2 at constant T.

Correct answer
B(a) towards reactant, (b) no change
Step-by-step explanation
Given reaction is endothermic.
On decreasing temperature backward reaction will be favoured.
On adding N2, pressure is increased at constant T, and volume would also be constant so no change is observed.
