Chemistry Question from JEE Main 2026 · 21 January, Shift 1

For the reaction, $N_{2}O_{4} \rightleftharpoons 2NO_{2}$ graph is plotted as shown below. Identify correct statements.

A. Standard free energy change for the reaction is $-5.40 \, \text{kJ mol}^{-1}$.

B. As $\Delta G^\circ$ in graph is positive, $N_{2}O_{4}$ will not dissociate into $NO_{2}$ at all.

C. Reverse reaction will go to completion.

D. When $1$ mole of $N_{2}O_{4}$ changes into equilibrium mixture, value of $\Delta G = -0.84 \, \text{kJ mol}^{-1}$.

E. When $2$ mole of $NO_{2}$ changes into equilibrium mixture, $\Delta G$ for equilibrium mixture is $-6.24 \, \text{kJ mol}^{-1}$.

Choose the correct answer from the options given below:
