In the citric acid cycle, malate is dehydrogenated to oxaloacetate in a highly endergonic reaction with a ΔG’o of +30 kJ mol-1:
Doss [256]

Answer :  The value of K_{eq} of this reaction is, 5.51\times 10^{-6}

At equilibrium, [L-malate] > [oxaloacetate]

Explanation :

The relation between the equilibrium constant and standard Gibbs free energy is:

\Delta G^o=-RT\times \ln K_{eq}

where,

\Delta G^o = standard Gibbs free energy  = +30 kJ/mol = +30000 J/mol

R = gas constant = 8.314 J/K.mol

T = temperature = 25^oC=273+25=298K

K_{eq}  = equilibrium constant  = ?

The given reaction is:

\text{L-malate}+NAD^+\rightleftharpoons \text{oxaloacetate}+NADH+H^+

\Delta G^o=-RT\times \ln K_{eq}

+30000J/mol=-(8.314J/K.mol)\times (298K)\times \ln K_{eq}

K_{eq}=5.51\times 10^{-6}

Therefore, the value of K_{eq} of this reaction is, 5.51\times 10^{-6}

As, the value of K_{eq} < 1 that means the reaction mixture contains reactants.

At equilibrium, [L-malate] > [oxaloacetate]
