Chemical Thermodynamics Part 3

For the reaction, N2O4⇌2NO2, graph is plotted as shown below. Identify correct statements.
A. Standard free energy change for the reaction is −5.40kJmol−1.
B. As ∆G⊖ in graph is positive, N2O4 will not dissociate into NO2 at all.
C. Reverse reaction will go to completion.
D. When 1 mole of N2O4 changes into equilibrium mixture, value of ∆G⊖=−0.84kJmol−1
E. When 2 mole of NO2 changes into equilibrium mixture, ∆G⊖ for equilibrium mixture is −6.24kJmol−1.
