ATP hydrolysis at pH 7 is accompanied by the release of hydrogen ion to the medium If the ΔG°’ for the reaction is -30.5 kJ/mol what is the ΔG° (that is, the free energy change for the same reaction with all components, including H+ , at a standard state of 1M)? ΔG° = kJ/mol   (number answer in 2 sf please) △G∘(prime)=△G∘+RTLn
