Phosphorus pentachloride decomposes to phosphorus trichloride at high temperatures according to the equation:
PCl5(g) = PCl3(g) + Cl2(gu)
at 250 Co , 0.125M PCl5 is added to the flask , if Kc=1.80, what are the equilibrium concentrations of each gas?
A) [PCl5]=0.0625M,[PCl3]=0.0335M, and [Cl2]=0.335M
B) [PCl5]=1.80M,[PCl3]=1.80M, and [Cl2]=1.80M
C) [PCl5]=0 M,[PCl3]=1.34M, and [Cl2]=1.34M
D) [PCl5]=0.00765M,[PCl3]=0.117M, and [Cl2]=0.0.117M
E) [PCl5]=3.96M,[PCl3]=3.83M, and [Cl2]=3.83M
