Question

Assume hydrolysis of ATP proceeds with G = -30 J/mol. RT = -2.5ATP + H2O -> ADP + PiWhich expression gives the ratio of ADP to ATP at equilibrium, if Pi = 1.0M?a. e^2b. e^3c. e^6d. e^12

Answer 1

Answer: (d) e^12

Explanation:

The relationship between the standard free energy change, ΔG, and the equilibrium constant, K at a particular temperature is represented Using the formula ΔG = -RTlnK, where G = -30, RT = -2.5 and [Pi] = 1

lnK = ΔG/-RT

lnK = -30/-2.5

lnK = 12

taking exponents of both sides

e^(lnK) = e^12

K = e^12
