Equilibrium: JEE Main 2026 Chemistry question

For the reaction, $\mathrm{N_2O_4\rightleftharpoons2NO_2}$, graph is plotted as shown below. Identify correct statements. A. Standard free energy change for the reaction is $-5.40$ kJ mol$^{-1}$. B. As $\Delta G^\ominus$ in graph is positive, $\mathrm{N_2O_4}$ will not dissociate into $\mathrm{NO_2}$ at all. C. Reverse reaction will go to completion. D. When 1 mole of $\mathrm{N_2O_4}$ changes into equilibrium mixture, value of $\Delta G^\ominus=-0.84$ kJ mol$^{-1}$. E. When 2 mole of $\mathrm{NO_2}$ changes into equilibrium mixture, $\Delta G^\ominus$ for equilibrium mixture is $-6.24$ kJ mol$^{-1}$. Choose the correct answer from the options given below :
