Answer #1

The given equation is

PCl5 (g) <=====> PCl3 (g) + Cl2 (g)

The expression for the equilibrium constant is given as

Keq = [PCl3][Cl2]/[PCl5]

Since all the reactants and the products are gaseous, we can express Keq in terms of the partial pressures of the gas.

We will need the partial pressures at equilibrium or the mole fractions and the total pressure of the gaseous system to calculate the value of Keq.
