Adenosine triphosphate, ATP, is used to store energy within biological systems. It releases that energy by losing a terminal phosphate group, Pi, to form adenosine diphosphate, ADP, through the hydrolysis reaction ATP(aq) + H2O(I) → ADP(aq) + Pi(aq) + H+(aq) . The standard reaction Gibbs energy, ΔrGΘ, for the hydrolysis of ATP to ADP is+ 10 kJ mol-1 at 298 K.This assumes that the concentration of hydrogen ions is 1 mol dm-3 . (a) In biochemistry, it is common practice to assume an alternative , and more realistic, standard state for which pH = 7. What is the corresponding standard reaction Gibbs energy, denoted ΔrGΘ, for this biological standardstate?
