Interpretation Introduction
Interpretation:
To calculate the reaction is reactant or product favored at equliribrium at 298 K and the reaction is more or less product favored at higher temperature.
Concept introduction:
The ΔS∘(system) can be calculated by the following expression,
ΔS∘(system)=ΔrS°=∑nS°(products)−∑nS°(reactants)
Enthalpy of formation of the reaction can be calculated by following expression,
ΔrH°=∑nΔfH°(products)−∑nΔfH°(reactants)
The Gibbs free energy or the free energy change is a thermodynamic quantity represented by ΔG∘. It is related to entropy and entropy by the following expression,
ΔG∘=ΔH∘−TΔS∘
Here, ΔrH∘ is the enthalpy change for the reaction.
If the value of ΔrG∘ is negative the reaction is product favored at equilibrium at 298 K.
