1E.11 Magnesium ions form complexes with both ATP and ADP. The standard enthalpy of reaction for the hydrolysis of ATP to ADP and inorganic phosphate (PO3, which is denoted Pi) has been measured at pH = 7 and 25 °C for two different concentrations of magnesium ions: [Mg2+(aq)]/(mmol dm³) 0 1.0 Ahydrolysis He/(kJ mol¯¹) -21.7 -25.1 The standard reaction enthalpy for the formation of the complex between Mg 2+ and ADP is +18.0 kJ mol¯1. Calculate the standard reaction enthalpy for the formation of the complex between Mg2+ and ATP. Why does the presence of magnesium ions affect the reaction enthalpy for the hydrolysis of ATP?
