For the endothermic reaction CaCO3 (s) CaO (s) CO2 (g) Le Cha^ telier's principle predicts that __________ will result in an inc
Firdavs [7]

Answer:

Increasing the temperature will result in increase in number of moles of CO_{2}

Explanation:

Concentration of pure solids and liquids remain constant throughout a reaction. Hence their concentrations terms are not involved in expression for equilibrium constant. Hence removing or adding solid CaCO_{3} will not affect change in number moles of CO_{2}.

In the forward direction, pressure increases due to formation of gaseous CO_{2}. Hence, according to Le-chatelier's principle, increase in pressure will result formation of more reactant.

As it is an endothermic reaction therefore heat is consumed in formation of CO_{2}. So, according to Le-chatelier;s principle, increasing the temperature will result in increase in number of moles of CO_{2}.

Correct option (D)
