Consider the values of `DeltaH("in" kJ mol^(-))` and for `DeltaS("in" mol^(-)K^(-1))` given for four different reactions. For which reaction will `DeltaG` increases the most (becoming more positive) when the temperature is increased form `0^(@)C "to" 25^(@)C`?

A

`DeltaH^(@)=50,DeltaS^(@)=50`

B

`DeltaH^(@)=90,DeltaS^(@)=20`

C

`DeltaH^(@)=-20,DeltaS^(@)=-50`

D

`DeltaH^(@)=-90,DeltaS^(@)=-20`

Text Solution

Verified by Experts

The correct Answer is:
C
Use the relation `DeltaG^(@)=DeltaH^(@)-TDeltaS^(@)`
