A sample problem for a chemistry student to solve from the subtopic Calculating the effect of changing the temperature on the equilibrium constant could be: What would be the new equilibrium constant (Kc) for the reaction 2NOCl (g) ↔ 2NO (g) + Cl2 (g) at 400 K, if the initial equilibrium constant at 300 K is 2.50 x 10^-3? Given that the enthalpy change of the reaction (∆H) is -91.84 kJ/mol and the entropy change of the reaction (∆S) is -188.8 J/mol K.
