At 250° 0.125 M PCl5 is added to the flask. If Kc = 1.80, what are the equilibrium concentrations of each gas?
A. [PCl5] = 0.00765 M, [PCl3] = 0.117 M, and [Cl2] = 0.117 M
B. [PCl5] = 0.0625 M, [PCl3] = 0.335 M, and [Cl2] = 0.335 M
C. [PCl5] = 1.80 M, [PCl3] = 1.80 M, and [Cl2] = 1.80 M
D. [PCl5] = 3.96 M, [PCl3] = 3.83 M, and [Cl2] = 3.83 M
