Otherwise, calculate the change in standard free energy using the following information. Show your work.
G°’ = -2.3 R T log Keq with the equilibrium conditions of [Product] = 10 and [Substrate] = 2, R =1.987 cal/mol and T = 298 K
Explanation / Answer
G°’ = -2.3 R T log Keq
= - 2.3 x 1.987 x 298 x [product] / [substrate]
= - 2.3 x 1.987 x 298 x 10 / 2
= - 6809.5 cal
standard free energy G = - 6809.5 cal
