Chapter 9, Problem 9.81CQ

Interpretation Introduction

Interpretation:

The enthalpy change for the given reaction should be calculated.

Concept Introduction:

Hess law states that the enthalpy change for multistep chemical reaction is the sum of all enthalpy changes. It can be written as;

  $\sum \Delta {\text{H}}_{\text{reaction}}\text{ =}\Delta \text{H1 + }\Delta \text{H2+}\Delta \text{H3}\mathrm{....}$
