Statement-1 : Many endothermic reactions that are not spontaneous at room temperature become spontaneous at high temperatures. Statement-2: Energy of the system increases with increase in temperature.
Statement -1: Many endothermic reactions that are not spontaneous at room temperature become spontaneous at high temperature. Statement-2: DeltaH^(@) of the endothermic recation increases with increases with increase in temperature.
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 .
Which of the reaction is expectd to be spontaneous at low temperatures and non-spontaneous at high temperatures:
An endothermic process is non-spontaneous at some temperature. It can be spontaneous at………….temperature.
An endothermic reaction which may be non spontaneous at low temperature because of entropy factor becomes spontaneous at high temperature.
The a reaction to be spontaneous at all temperature
A reaction is spontaneous at low temperature but non- spontaneous at high temperature. Which of the following is true for the reaction?
For a reaction to be spontaneous at all the temperature:
