Assertion: For an ideal binary solution, the excess molar enthalpy is zero.
Reasoning: Ideal solutions are those in which the interactions between the two components are the same as the interactions between like molecules.
Both assertion and reasoning are true and the reasoning is the correct explanation of the assertion.

Assertion is false but the reasoning is true
Ideal solutions are those in which the interactions between the two components are the same as the interactions between like molecules. In such solutions, the excess molar enthalpy is zero. This is because the enthalpy change due to mixing is equal to the sum of the enthalpy changes of the two pure components, and for an ideal solution, there is no enthalpy change due to mixing.
