Question

For the reaction $N_{2} O_{4} ⇌ 2 {NO}_{2}$ 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 ${ΔG}^{⊝}$ 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 ${ΔG}^{⊝} = - 0.84 kJ mol⁻¹.$
E. When 2 mole of ${NO}_{2}$ changes into equilibrium mixture, ${ΔG}^{⊝}$ for equilibrium mixture is $- 6.24 kJ mol⁻¹.$

$(A) Δ_{r} G ° = G_{B} ° - G_{A} ° = + v e$

$(B) Δ_{r} G ° = + v e, N_{2} O_{4} will partially dissociate into N O_{2} .$

$(C) For reverse reaction$

$It is partially completed as there is equilibrium at E.$

$(D) For 1 mole N_{2} O_{4}; Δ_{r} G ° = - 0.84 {kJ mol}^{- 1}$

$(E) For 2 mole N O_{2}; Δ_{r} G ° = - 5.4 - 0.84$

$= - 6.24 {kJ mol}^{- 1}$
