The following equation represents the decomposition of a generic diatomic element in its standard state.
1/2 X2 (g) → X (g)
Assume that the standard molar Gibbs energy of formation of X (g) is 5.14 kJ • mol-1 at 2000 K and -51.10 kJ • mol-1 at 3000 K. Determine the value of K (the thermodynamic equilibrium constant) at each temperature.
Assuming that ΔH°rxn is independent of temperature, determine the value of ΔH°rxn from these data.
