The condition of spontaneity of a process is
- A lowering of enthropy at constant temperature and pressure
- B lowering of Gibbs free energy of system at constant temperature and pressure
- C increase of entropy of system at constant temperature and pressure
- D increase of Gibbs free energy of the universe at constant temperature and pressure
Answer & Solution
Correct Answer
(B) lowering of Gibbs free energy of system at constant temperature and pressure
Step-by-step Solution
Detailed explanation
From Gibbs Helmholtz equation, \[ \Delta G=\Delta H-T \Delta S \] A process will be spontaneous, if \[ \Delta G=-\text { ve } \]
