Chapter 21, Problem 76AP

Interpretation Introduction

Interpretation:

The standard enthalpy of formation for ClOis to be calculated.

Concept introduction:

The standard enthalpy of formation is the change in the energy consumed or released when one mole of a substance is formed under the standard condition.

The change in enthalpy $\Delta H°$ is given by the expression, which is as follows:

$\Delta H°$= ${\displaystyle \sum BE\left(\text{reactants}\right)-}{\displaystyle \sum BE\left(\text{products}\right)}$.

Here, $BE$ is the bond energy.

The standard enthalpy of formation is given by the expression, which is as follows:

$\Delta H^{°}{}_{\text{reaction}}={\displaystyle \sum \Delta H^{°}{}_f}\left(p\right)-{\displaystyle \sum \Delta H^{°}{}_f\left(r\right)}.$

Here, p is the product and r is the reactant.
