a critical reaction in the production of energy to do work or drive chemical in biological systems is the hydrolysis of adenosine triphosphate, ATP to adenosine diphosphate ADP as described by ATP(aq) + H20(l) ----> ADP(aq) + HPO4^2- (aq) for which change in G rxn = -30.5 kJ/mol at 37.0 celsius and pH 7.0 . Calculate the value of change in G rxn in a biological cell in which ATP=5.0mM [ADP]=0.20mM and [HPO4^2-]=5.0mM change in G rxn=________kJ/mol
