Question
Which of the following options will be correct for the stage of half completion of the reaction A ⇌ B.
Options
∆GΘ = 0
∆GΘ > 0
∆GΘ < 0
∆GΘ = – RT ln 2
Solution
∆GΘ = 0
Explanation:
A ⇌ B
∆GΘ = – RT In K
At the stage of half completion of reaction [A] = [B],
Therefore, K = 1. Thus, ΔGΘ = 0.
