Why must the physical states of all reactants and products be specified in a thermochemical equation?

Expert Solution & Answer
Check Mark
Interpretation Introduction

Interpretation:

Reason for why the physical states of all reactants and products be specified in a thermochemical equation has to be explained.

Explanation of Solution

If ΔH is given in a chemical equation, then it is a thermochemical equation. The enthalpy of a compound depends on its physical state. The value of enthalpy change varies according to the physical state. Therefore, it is important to include the physical states of all reactants and products be specified in a thermochemical equation.
