Which of the following statements is correct for a reversible process in the state of equilibrium?

Which of the following statements is correct for a reversible process in the state of equilibrium?

$Δ G = - 2.30 R T \log K$
$Δ G = 2.30 R T \log K$
$Δ G^{o} = - 2.30 R T \log K$
$Δ G^{o} = 2.30 R T \log K$

Solution

For a reversible process at equilibrium

Δ G = 0 = Δ G^{o} + R T \ln K (Q = K)

i.e.

Δ G^{o} = - 2.303 R T \log K
