AiH,,AiH, and AiH, of an element M are 750, 1500 and 7750 kJ mol respectively. The

This reaction has an equilibrium constant of at 298K.

Calculate Kp for each reaction and predict whether reactant or products will be favoured at equilibrium.

A)

B)

C)

A) : : reactants are favoured

B) : : products are favoured

C) : : reactants are favoured

Explanation:

1. We need to calculate the equilibrium constant for the reverse equation of above chemical equation, which is:

As is less than 1, reactants will be favored at equilibrium.

2. We need to calculate the equilibrium constant for the half equation of above chemical equation, which is:

As is greater than 1, products will be favored at equilibrium.

3.  We need to calculate the equilibrium constant for the reverse and twice the equation of above chemical equation, which is

As is less than 1, reactants will be favored at equilibrium.
