STANDARD Chemistry Gibbs Free Energy MCQ Question

Type: MCQ-conceptual-Medium-Class 11

The incorrect expression among the following is

A

For isothermal process Wₙₑᵥₑᵣₛᵢᵦₗₑ = -nRT ln V₂/V₁

B

ln Kₑᵩ = -ΔH° + TΔS°/RT

C

ΔGₛᵧₛₜₑₘ/ΔSₜₒₜₐₗ = -T (at constant P)

D

K = e⁻ΔG°/RT

Correct Answer

Option C

Detailed Explanation

The expression ΔGₛᵧₛₜₑₘ/ΔSₜₒₜₐₗ = -T is incorrect because it does not correctly relate the Gibbs free energy change and entropy change. The correct relationship involves the equilibrium constant and the standard Gibbs free energy change.
