can someone clarify why enzymes do not lower gibbs free energy?
when faced with this question, i answered that they do.
the following is my reasoning.
enzymes lower Ea of a reaction. since the delta H of a reaction depends on the Ea of the reaction, the lower the Ea, the lower the delta H. gibbs free energy = Delta H - T*delta S.
so shouldnt gibbs free energy decrease proportionally with delta H?
