Biochemistry Thermodynamics: Practice Problem 3

ATP hydrolysis at pH 7.0 is accompanied by release of hydrogen ion to the medium
ATP4- + HO   ↔ ADP3- + HPO­42- + H+

If the ΔG˚’ for this reaction is -30.5 kJ/mol, what is ΔG˚ (that is, the free energy change for the same reaction with all components including H+, at a standard state of 1M)?
