The value of the standard free energy (∆G°’) for the hydrolysis of ATP (ATP + H2O -> ADP + Pi)...
The value of the standard free energy (∆G°’) for the hydrolysis of ATP (ATP + H2O -> ADP + Pi) is relatively difficult to determine because of the small concentration of ATP remaining at equilibrium. The value can be determined from the equilibrium constant of two related chemical reactions.
Glucose-6-phosphate + H2O -> glucose + Pi ; k’eq = 270
ATP + glucose -> ADP + glucose-6-phosphate ; K’eq = 890
From this information, calculate the standard free energy of ATP hydrolysis ((∆G°’) at 298K.
Homework Answers
the relation between Gibbs free energy and equilibrium constant is
So, for first equation 
Applying the same formula for second equation, we get, delta Go = 16.8KJ
Adding equation 1 and 2 we get,
glucose-6-phosphate+H2O+ATP+Glucose ------> glucose +Pi+ADP+glucose-6-phosphate. delta Go=30.67KJ
Overall reaction is ATP + H2O -----> ADP + Pi. delta Go = 30.67KJ is the final answer

We have seen all term that cells use the hydrolysis of high energy phosphate from ATP to make metabolic reactions thermodynamically favorable. Whereas most enzymes that utilize ATP hydrolyze between the b and g phosphates (yielding ADP + Pi), some enzymes hydrolyze ATP between the a and b phosphates (yielding AMP and PPi). ∆G°’ of phosphate hydrolysis is -31 kJ/mol for ATP + H2O --> ADP + Pi, and ∆G°’ of phosphate hydrolysis is -46.5 kJ/mol for ATP + H2O...
