JEE Main 2020Chemical Equilibrium Question with Solution

JEE Main 2020 (05 Sep Shift 1)

Question

Consider the following reaction:
N2O4(g)=2NO2(g): ΔH0=+58k
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.

Choose an option

Show full solutionCorrect option: C
Correct answer
C(a) towards reactant, (b) no change

Step-by-step explanation

(i) As reaction is endothermic so on decrease in temperature equilibrium shift in reactant side.
(ii) On increase in pressure by adding inert gas at same temperature, no shifting will take place
