PROBLEMS AND EXAMPLES 107

adenosine 5′-diphosphate ADP was substituted for ATP. The hydrolysis reaction

producing adenosine 5′-monophosphate AMP

ADP+H 2 O→ADP+phosphate

resulted in a temperature change of
T= 0 .100 K. Find
H◦for the reaction

2ADP→AMP+AT P

(The symbol
H◦is used to indicate a standard enthalpy change relative to a defined

concentration under specific solution conditions.)
