Question

Which statement about enthalpy is not correct?

A. Enthalpy can be measured in joules per mole
B. Enthalpy is an intensive property
C. Enthalpy is a state function
D. Change in enthalpy is negative for an exothermic reaction

Answer 1

Enthalpy is an extensive property, not an intensive property.

Step-by-step explanation:

The statement that is not correct is B. Enthalpy is an extensive property, not an intensive property.

An intensive property is one that does not depend on the amount of material being dealt with, while an extensive property does depend on the amount of material. Enthalpy is an extensive property because it depends on the amount of substance involved in a reaction.

Therefore, statement B is the one that is not correct.
