Question

Indicate which direction the reaction Ishown below would shift in response to the change described & why? Ha(g) + CO2(gl H2O(g) + Coigo АН ran +9.9kcal a.) addition of CO2 b.) addition of H2O ci) addition of a catalyst d.) Increase in temperature eil decrease in volume of the containe

Answer 1

This is related to Lechatlier principle application.

(a) addition of CO2 - increases the reactants and to compensate or to establish equilibrium, the equilibrium will shift to products.

(b) addition of H2O - increases the amount of products and equilibrium will shift to reactants to compensate the change.

(c) addition of catalyst - no effect on equilibrium.

Catalyst only increases the rate of reaction and equilibrium tend to establish fast.

(d) increase in temperature - since this is endothermic reaction and heat is a consumed in reaction. So, increase in temperature causes equilibrium shift to forward direction towards products.

(e) decrease in volume of container - nothing but it is increasing in pressure and equilibrium will shift to less number of gas moles.

Here, number of moles of products and reactants are same. So, no effect in decrease in volume of container.
