NEET Chemistry Enthalpy Assertion Reason Question
Assertion (A): The net enthalpy change of a reaction can be determined using the bond enthalpies of reactants and products. | Reason (R): Bond enthalpy values are exact and provide precise enthalpy changes for all reactions.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true as bond enthalpies can be used to approximate the net enthalpy change, but the reason is false because bond enthalpy values are approximate, not exact.
