A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by the reaction:

for which = -30.5 kJ/mol at 37.0 °C and pH 7.0.
Calculate the value of in a biological cell in which [ATP] = 5.0 mM, [ADP] = 0.80 mM, and = 5.0 mM.
A. What is the in kJ/mol?
B. Is the hydrolysis of ATP spontaneous under these conditions? Yes / No.
