Question

1)The

H2/COratio in mixtures of carbon monoxide and hydrogen(called synthesis gas)is increased by the water-gas shift reaction CO(g)+H2O(g)?CO2(g)+H2(g), which has an equilibrium constant Kc=4.24at 800 K.

Calculate the equilibriumconcentrations of CO2, H2, CO,and H2O at 800 K if only CO andH2Oare present initially atconcentrations of 0.148M.

2)The equilibrium constant

Kpfor the reaction C(s)+H2O(g)???CO(g)+H2(g)
is 2.44 at 1000 K. The initial partial pressuresare PH2O= 1.25atm, PCO= 1.07atm, and PH2 =1.39atm.

What is the equilibrium partial pressure ofH2O, CO, and H2?

3)When a mixtureof

PH3,P2,and H2 comes to equilibrium at 873 K according to thereaction
2PH 3(g)???P2(g)+3H2(g)Kp= 398 at 873 K,
where Pp2 =0.417atmand PH2 =0.828atm.

what is P ph3 ??

Show work please!
