The a reaction to be spontaneous at all temperature

A reaction at 1 bar is non-spontaneous at low temperature but becomes spontaneous at high temperature. Identify the correct statement about the reaction among the following:

For a reaction to be spontaneous at all the 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: All endothermic reactions which are non-spontaneous at room temperature become spontaneous at high temperatures. Reason : Endothermic reactions become spontaneous if DeltaS is positive and TDeltaS gt DeltaH .

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.

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