Chapter 10, Problem 13PE

Interpretation Introduction

Interpretation:

The thermochemical equation of generating $1\text{mole}$ of liquid water by the reaction of gaseous hydrogen and oxygen in two forms is to be stated.

Concept introduction:

A balanced equation which involves the change of enthalpy or energy is known as thermochemical equation. There are two forms of writing the thermochemical equation. In first form, ${\Delta }_{\text{r}}\text{H}$ is written to the right side of the equation. In the second form, ${\Delta }_{\text{r}}\text{H}$ is added to the reactant side.
