The following equation represents the decomposition of a generic diatomic element in its standard state.
1/2X2 (g) ⇌ X (g)
Assume that the standard molar Gibbs energy of formation of X(g) is 4.82 kJ·mol–1 at 2000 K and –58.08 kJ·mol–1 at 3000 K.
a. Determine the value of K (the thermodynamic equilibrium constant) at each temperature.
b. Assuming that ΔH°rxn is independent of temperature, determine the value of ΔH°rxn from these data.
