According to Hess's Law:

A.The rate of reaction depends only on temperature

B.The enthalpy change of a reaction is the same regardless of the pathway

C.Entropy always increases in spontaneous reactions

D.The equilibrium constant equals the rate constant

Explanation

Core Concept

Hess's Law states that the total enthalpy change for a reaction is the same regardless of the number of steps or the pathway taken, because enthalpy is a state function.

Correct Answer

BThe enthalpy change of a reaction is the same regardless of the pathway
