An endothermic process is non-spontaneous at some temperature. It can be spontaneous at………….temperature.

Assertion (A): An exothermic process, non-spontaneous at high temperature, may become spontaneous at low temperature. Reason (R ) : With decrease in temperature, randomness (entropy) decreases.

Assertion : An exothermic process which is non-spontaneous at high temperature may become spontaneous at low temperature. Reason : Spontaneous process is an irreversible process and may be reversed by some external agency.

A process is spontaneous at all temperatures when
