The standard Gibb's free energy change, Δ G ∘ is related to equilibrium constant, K p as

Δ G ∘ and K p are related as Δ G ∘ = − RT ln K p ⇒ ln K p = RT Δ G ∘ ⇒ K p = e − Δ G ∘ / RT

The standard Gibb's free energy change, $Δ G^{\circ}$ is related to equilibrium constant, $K_{p}$ as

Options:

Answer:

Solution:

$Δ G^{\circ}$ and $K_{p}$ are related as $Δ G^{\circ} = - RT ln K_{p} \Rightarrow ln K_{p} = \frac{Δ G ^{\circ}}{RT} \Rightarrow K_{p} = e^{- Δ G^{\circ} / RT}$
