Given that the enthalpy change of the reaction, Delta H = 18.8 kJ. So the reaction as written is endothermic. That is, heat is absorbed in the forward reaction.
According to Le Chatelier principle, any reaction at equilibrium when disturbed will act in a way to oppose the external disturbance.
As temperature is increased, the reaction will proceed in a direction in which the excess heat energy added is absorbed. As the forward reaction is endothermic, the excess heat energy will be absorbed if the forward reaction is dominant.
So as the temperature increases forward reaction takes place. Reactants concentration will decrease and products concentration will increase.
Ans: Concentration of CH2Cl2 will increase.
