What is the change in the equilibrium constant (Kc) for the exothermic reaction A + B ⇌ AB at 298 K if the temperature is increased from 298 K to 350 K? Given that the enthalpy change (ΔH) for the reaction is -50 kJ/mol and the initial concentration of A and B are 0.1 mol/L and 0.2 mol/L respectively.
