Interpretation:
The equilibrium constant is greater than one, the reaction is spontaneous when all the reactants and products are in their standard states and the reaction is always exothermic for a reaction with negative
value, are to be explained.
Concept introduction:
The quantity that predicts the spontaneity of a process is called Gibbs free energy. The mathematical equation is as follows:
Here,
is the change in standard Gibbs free energy,
is the standard entropy change of a system, and
Entropy is a thermodynamic function. It is the measure of randomness or disorder of the system. The unit of entropy is
The reaction is spontaneous if

- Adenosine triphosphate, ATP, is used as a free-energy source by biological cells. (See the essay on page 624.) ATP hydrolyzes in the presence of enzymes to give ADP: ATP(aq)+H2O(l)ADP(aq)+H2PO4(aq);G=30.5kJ/molat25C Consider a hypothetical biochemical reaction of molecule A to give molecule B: A(aq)B(aq);G=+15.0kJ/molat25C Calculate the ratio [B]/[A] at 25C at equilibrium. Now consider this reaction coupled to the reaction for the hydrolysis of ATP: A(aq)+ATP(aq)+H2O(l)B(aq)+ADP(aq)+H2PO4(aq) If a cell maintains a high ratio of ATP to ADP and H2PO4 by continuously making ATP, the conversion of A to B can be made highly spontaneous. A characteristic value of this ratio is [ATP][ADP][H2PO4]=500 Calculate the ratio [B][A] in this case and compare it with the uncoupled reaction.
