1.	Assertion : If both `DeltaH^(@) and DeltaS^(@)` are positive then reaction will be spontaneous at high temperature. Reason : All processes with positive entropy chang are spontaneous.A. If both assertion and reason are true and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - C Spontaneity of a process depends upon `DeltaG^(@)` which combines both factors `DeltaH^(@)` and `DetlaS^(@)`. `DeltaG^(@)=DeltaH^(@)-TDeltaS^(@)` For the spontaneity, `DeltaG^(@)` should be negative. If `DeltaH^(@)` is `+ve , DeltaS^(@)` is +ve then, `DeltaG^(@)` to be `-ve` only when `TDeltaS gt DeltaS` which is possible at high temperature.
