For the reaction, $\mathrm{N}_2 \mathrm{O}_4 \rightleftharpoons 2 \mathrm{NO}_2$, graph is plotted as shown below. Identify correct statements.
A. Standard free energy change for the reaction is $-5.40 \mathrm{~kJ} \mathrm{~mol}^{-1}$.
B. As $\Delta \mathrm{G}^{\circ}$ in graph is positive, $\mathrm{N}_2 \mathrm{O}_4$ will not dissociate into $\mathrm{NO}_2$ at all.
C. Reverse reaction will go to completion.
D. When 1 mole of $\mathrm{N}_2 \mathrm{O}_4$ changes into equilibrium mixture, value of $\Delta \mathrm{G}^{\ominus}=-0.84 \mathrm{~kJ} \mathrm{~mol}^{-1}$
E. When 2 mole of $\mathrm{NO}_2$ changes into equilibrium mixture, $\Delta \mathrm{G}^{\ominus}$ for equilibrium mixture is $-6.24 \mathrm{~kJ} \mathrm{~mol}^{-1}$.
