(A) The reaction is $PCl_5 \rightleftharpoons PCl_3 + Cl_2$. At equilibrium,the number of moles of each species is $n(PCl_5) = 2$,$n(PCl_3) = 2$,and $n(Cl_2) = 2$. Total moles $n_{total} = 2 + 2 + 2 = 6 \ mol$. The mole fraction of each species is $x = \frac{2}{6} = \frac{1}{3}$. The partial pressure of each species is $P_i = x_i \times P_{total} = \frac{1}{3} \times 3 \ atm = 1 \ atm$. $K_p = \frac{P(PCl_3) \times P(Cl_2)}{P(PCl_5)} = \frac{1 \times 1}{1} = 1 \ atm$.
