Chapter 5.7, Problem 1RC

Interpretation Introduction

Interpretation: The standard enthalpy of formation for ${\text{AlCl}}_{\text{3}}\left(\text{s}\right)$ is relating to the enthalpy change of which reaction should be determined.

Concept Introduction:

Standard enthalpy of the reaction, ${\text{Δ}}_{\text{r}}{\text{H}}^{\text{o}}$, is the change in enthalpy that happens when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.

Enthalpy of the reaction, ${\text{Δ}}_{\text{r}}\text{H}$, is the change in enthalpy that happens when matter is transformed by a given chemical reaction
