Chapter 8, Problem 135QP

Interpretation Introduction

Interpretation:

The bond enthalpy in kilojoule per mole is to be calculated.

Concept introduction:

The formula to calculate the work done can be represented as follows:

$\text{work done}=\text{Force}\times \text{distance}\text{.}$

While adding the thermochemical equations the enthalpy change value is also added, which gives the enthalpy change of the net reaction.

On reversing any equation the sign of enthalpy change value is changed to the opposite sign.
