Interpretation:
The equilibrium constant at a given temperature for the given reaction is to be calculated; also, the reason for the difference in ΔG∘ values and explanation related to reactions is to be determined.
Concept Introduction:
The equilibrium constant of the reaction is calculated by using the formula,
ΔG∘=−RTlnK
The difference in the ΔG∘ values is either due to enthalpy term or due to entropy term.
