SUMMARY
The equilibrium constant (Kp) for the reaction H2 + I2 → 2HI at 718 K is established at 50.2. The standard enthalpy change (ΔH) for the reaction is 25 kJ mol-1. To calculate the entropy change (ΔS) at 718 K, one can utilize the relationship between Gibbs free energy (ΔG), enthalpy, and entropy, applying the formula ΔG = ΔH - TΔS. This allows for the determination of standard entropy at the specified temperature.
