Initially, 0.65 mol of PCl5 is placed in a 1.0 L flask. At equilibrium, there is 0.15 mol of PCl3 in the flask. What is the equi
borishaifa [10]

Answer : The equilibrium concentration of PCl_5 is, 0.50 M

Explanation : Given,

Initial moles of PCl_5 = 0.65 mole

Volume of solution = 1.0 L

Moles of PCl_3 at equilibrium = 0.15 mole

The balanced equilibrium reaction will be,

                          PCl_5\rightleftharpoons PCl_3+Cl_2

Initial moles     0.65        0         0

At eqm.           (0.65-x)     x         x

Moles of PCl_3 at equilibrium = x = 0.15 mole

Moles of Cl_2 at equilibrium = x = 0.15 mole

Moles of PCl_5 at equilibrium = (0.65-x) = (0.65-0.15) = 0.50 mole

Now we have to calculate the concentration of PCl_3,Cl_2\text{ and }PCl_5 at equilibrium.

Formula used : Concentration=\frac{Moles}{Volume}

\text{Concentration of }PCl_3=\frac{\text{Moles of }PCl_3}{\text{Volume of solution}}=\frac{0.15mole}{1.0L}=0.15M

\text{Concentration of }Cl_2=\frac{\text{Moles of }Cl_2}{\text{Volume of solution}}=\frac{0.15mole}{1.0L}=0.15M

\text{Concentration of }PCl_5=\frac{\text{Moles of }PCl_5}{\text{Volume of solution}}=\frac{0.50mole}{1.0L}=0.50M

Therefore, the equilibrium concentration of PCl_5 is, 0.50 M
