The standard biological reaction Gibbs energy for the removal of the phosphate group from adenosine monophosphate is 14 kJ mol-1 at 298 K. What is the value of the thermodynamic standard reaction Gibbs energy?

Answer: K = 284

Explanation:

Gibbs free energy (DG) = RT (InK)

Where:

R = Gas constant = 8.314J/K/mol = 0.008314KJmol/K

T = temperature in Kelvin = 298K

K = dissociation rate

DG = 14

DG = RT (InK)

14 = 0.008314 * 298 * (InK)

14 = 2.477572 * InK

Ink = (14 : 2.477542)

InK = 5.6507619

K = 284
