Question

Consider the reaction: PCl5 (g) <--> PCl3 + Cl2 K= 5.0 x 10-2at 240 degrees C.
(A) In an experiment, 0.200 mol of PCl5, 0.500 mol of PCl3, and0.300 mol of Cl2 are mixed in a 2.00 L container. Calculate theequilibrium concentrations of PCl5, PCl3, and Cl2.

Consider the reaction N2O4 (g) <--> 2NO2 (g) at a temperaturewhere Kp = 0.131 atm.
(A) A flask initially contains N2O4 at 1.000 atm pressure.Calculate the pressures of NO2 and N2O4 at equilibrium.
