Answer. Hydrogen with iodine forms hydrogen iodide, the balanced chemical equation is
CO(g) + 3H2(g) <======> 2HI(g)
For this reaction; the rate of forward reaction is:
Rf =Kf [H2][I2]
The rate of reverse reaction is:
Rf =Kf [HI]2
The equilibrium constant expression for this reaction is
[HI]2
Kc =
[H2][I2]
iv. CO(g)+ 3H2(g) <====> CH4(g) + H2O(g)
Carbon monoxide with hydrogen forms methane and water
For this reaction; the rate of forward reaction is:
Rf = kf [CO] [H2]3
The rate of reverse reaction;
Rr = kr [CH4][H20]
The expression for the equilibrium constant for this reaction is
[CH4l lH2O]
Kc = [CO] [H2]3
