Question
Chapter 12, Problem 60QAP
Interpretation Introduction
Interpretation:
The change in enthalpy for the reaction needs to be determined.
Concept introduction:
For a general equilibrium reaction as follows:
The expression for the equilibrium constant is represented as follows:
Here, to calculate the equilibrium constant, the values of partial pressure of all the species in reactant and product side are required.
The equilibrium constant of a reaction depends on the temperature. The relation is given by Van’t Hoff equation which is as follows:
Here, K is equilibrium constant, R is Universal gas constant, T is temperature and
