Chapter 6, Problem 6B.1BE

(i)

Interpretation Introduction

Interpretation:

Under the given conditions, the equilibrium constant $K$ at temperature $1600\text{K}$ has to be calculated.

Concept Introduction:

The standard reaction enthalpy is equal to the sum of standard enthalpy of products minus standard enthalpy of reactants.  The relation between standard reaction enthalpy and equilibrium constant is Van’t Hoff equation.
