Question
Assertion: DH is positive for endothermic reactions.
Reason: If total enthalpies of reactants and products are HR &HP respectively then for an endothermic reaction HR<HP.
- If both Assertion and Reason are true and the Reason is correct explanation of the Asser- tion.
- If bothAssertion and Reason are true but Rea- son is not correct explanation of the Asser- tion.
- If Assertion is true but the Reason is false.
- If Assertion & Reason both are false
The correct answer is: If both Assertion and Reason are true and the Reason is correct explanation of the Asser- tion.
