For the reaction PCl5 (g) PCl3 (g) + Cl2 (g) , Kc = 0.0454 at 261 °C.  If a vessel is filled with theses gases such that the initial concentrations are [PCl5] = 0.2 M, [PCl3] = 0.2 M, and [Cl2] = 2.25 M, the value of the reaction quotient is:

▸ Qc = 1.8

▸ Qc = 0.56

▸ Qc = 2.8

▸ Qc = 0.0454

▸ Qc = 1
