Thermodynamics of ATP Hydrolysis

This article discusses the thermodynamics of the hydrolysis of ATP to ADP and inorganic phosphate.

The standard state is a set of conditions under which the free energy of a substance is 0 kJ mol-1.

The equilibrium constant is the ratio of the concentrations of products to reactants at equilibrium.

The equilibrium constant can be used to calculate the free energy change of a reaction using the following equation: ∆G = -RT ln(K).

The ∆G of the hydrolysis of ATP is -30.5 kJ mol-1.
