Consider the reaction:        2 H2S(g) ⇌ 2 H2(g) + S2(g)                   Kp = 2.40 x 10-4 @ 1073K A reaction mixture contains 0.112 atm H2, 0.055 atm S2, and 0.445 atm H2S. a) Calculate the reaction quotient (Qp) (3pts)    b) What direction is the reaction going. (Left      Right     Neither) (2pts) c) Calculate the Kc for the reaction given above. (2 pts) **This question copyright of Dr. Simon Tang @ Valencia College.
