NEET Chemistry Hess's Law Assertion Reason Question
Assertion (A): The enthalpy change of a reaction is independent of the path taken, whether in one step or several steps. | Reason (R): Hess's Law states that the standard reaction enthalpy is the sum of the standard enthalpies of the intermediate 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 but R is true.
Correct Answer
Detailed Explanation
Hess's Law demonstrates that enthalpy is a state function and thus independent of the path of the reaction, supporting the assertion with the reason.
