Thermodynamics and Free Energy - Medical Science

Q1:

If the enthalpy change for a reaction is zero, ΔG° is equal to

A TΔS°

B -TΔS°

C -ΔH°

D lnKeq

ANS:B - -TΔS°

Free energy of a chemical system is the energy that is available in doing work. It is the driving force that brings about a chemical change.
