Question
Chapter 21, Problem 46PS
Interpretation Introduction
Interpretation:
To calculate the enthalpy and free energy change for the given reaction and check whether the reaction is exothermic or endothermic.
Concept introduction:
The Gibbs free energy or the free energy change is a
The enthalpy change is expressed by the formula,
If the value of enthalpy change is negative, the reaction is exothermic.
If the value of free energy change is negative, then the reaction is product-favored at equilibrium.
