Question

∆ H does not depend on the path of a reaction, but ∆ q does.

True

False

Answer 1

Enthalpy change (∆H) is a State Function because it depends only on two thermodynamic properties of the state at any given moment. (like Tand P, or T and entropy (S), or any pair of other state functions).

Hence we say that It does not depend on the path followed by the substance to get there.

On the other hand, Heat change (∆q) is a path function because it depends on how the thermodynamic system changes from the initial state to final state.

Hence The given statement is TRUE.
