Chapter 9, Problem 61E

Interpretation Introduction

Interpretation: The $\Delta \text{H}$

value for the following reaction needs to be determined and whether it is useful for the production of ammonia or not needs to be explained:

  

Concept Introduction: For the overall processes, the enthalpy change can be determined by adding the enthalpy change of all the steps involved in the process is known as Hess’s Law. The equation to show Hess’s law is:

  ${\text{ΔH}}_{\text{total}}{\text{= ΔH}}_{\text{1}}{\text{+ΔH}}_{\text{2}}{\text{+ΔH}}_{\text{3}}\text{+}\mathrm{...}{\text{+ΔH}}_{\text{n}}$
