Question:

Consider the reaction equilibrium Ice(Greater volume)⇌Water(Lesser volume) -X kcal. The favourable condition for forward reaction are:

high temperature, low pressure and excess of ice

low temperature, low pressure and excess of ice

low temperature, high pressure and excess of ice

high temperature, high pressure and excess of ice

Solution:

According to the Le-chatler's principle the reaction will proceed in the direction where volume will be reduced. At High temperature, high pressure and excess of Ice (more concentration of reactants) the forward reaction is favored. Hence option D is the correct answer.
