1.	A chemical reaction cannot occur at all isA. `DeltaH` values is positive and `DeltaS` value if negativeB. `DeltaH` value is negative and `DeltaS` value is positiveC. `DeltaH` and `DeltaS` values are negative but `DeltaH lt TDeltaS`D. `DeltaH` and `DeltaS` values are positive but `DeltaH lt T DeltaS`
Answer» a. DeltaG is +ve` if `DeltaH is+ve` and `DeltaS is -ve` . Thus, reaction in non-spontaneous. Hence (a) is the correct answer.
