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.
