In the absence of ATP, glucose-6-phosphate is unstable at pH7, in the presence of enzyme glucose-6-phosphatase, it undergoes hydrolysis:
glucose-6-phosphate + H2O -> glucose + phosphate
Calculate delta G0' at 25C for the hydrolysis of glucose-6-phosphate.
I was going to use formula: delta G = delta G0' + RT ln K
But I don't have other information. Is there another approach or am I missing some information given here?
