Assertion: A non-spontaneous endothermic reaction at room temperature may be spontaneous at high temperature.
Reason: At high temperature `TDeltaS` becomes more than `DeltaH` .

The a reaction to be spontaneous at all temperature

For a reaction to be spontaneous at all temperatures

Which of the reaction is expectd to be spontaneous at low temperatures and non-spontaneous at high temperatures:

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 .

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

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

For a reaction to be spontaneous at all the temperature:

Assertion (A): May endothermic reactions that are not spontaneous at room temperature become spontaneous at high temperature. Reason (R ) : Entropy of the system increases with increase in temperature.
