Here's a specific problem for the student to solve:Consider the reaction A(g) + B(g) ↔ C(g) with a standard enthalpy change of reaction (ΔH°rxn) of -50 kJ/mol at 298 K. If the initial concentrations of A and B are both 1.0 M, what will be the equilibrium concentration of each gas at 298 K? The equilibrium constant (Kc) for the reaction at 298 K is 2.75 x 10^-2.
