For an edothemic reaction, `DeltaH` is positive.

For an exothermic reaction, DeltaH is positive.

Assertion : DeltaH for an exothermic reaction is negative nad for an endothermic reaction is positive. Reason : Enthalpy is an extensive property.

For a chemical reaction, DeltaH is negative and DeltaS is negative and DeltaS is negative . This reaction is

Heat of reaction (DeltaH) is given by
