Gibbs energy of an enzyme-catalyzed reaction

Evaluate the standard reaction Gibbs energy at 25°C for the reaction C02(g) + H20(1) — H2C03(aq) catalyzed by the enzyme carbonic anhydrase in red blood cells. 

Strategy Obtain the relevant standard enthalpies of formation and standard entropies from the Resource section. Then calculate the standard reaction enthalpy and the standard reaction entropy from 

The standard reaction entropy was calculated in the hrfef illustration in Section 2.5  

Self-test 4.6 ) Use the information in the Resource section to determine the standard reaction Gibbs energy for 3 Ojfg) - 2 03(g) from standard enthalpies of formation and standard entropies.
