Equilibrium in Chemical Processes - Dynamic Equilibrium

For the following equilibrium, K_c = 6.3 × 10¹⁴ at 1000 K

\[\ce{NO (g) + O3 (g) ⇌ NO2 (g) + O2 (g)}\]

Both the forward and reverse reactions in the equilibrium are elementary bimolecular reactions. What is K_c, for the reverse reaction?

Describe the effect of Removal of CH₃OH on the equilibrium of the reaction:

\[\ce{2H2(g) + CO (g) ⇌ CH3OH (g)}\]

Describe the effect of addition of H₂  on the equilibrium of the reaction: 

\[\ce{2H2(g) + CO (g) ⇌ CH3OH (g)}\]

Dihydrogen gas used in Haber’s process is produced by reacting methane from natural gas with high-temperature steam. The first stage of two-stage reaction involves the formation of CO and H₂. In the second stage, CO formed in the first stage is reacted with more steam in water gas shift reaction,

\[\ce{CO (g) + H2O (g) ⇌ CO2 (g) + H2 (g)}\]

If a reaction vessel at 400°C is charged with an equimolar mixture of CO and steam such that `"p"_"CO" = "p"_("H"_2"O")` = 4.0 bar, what will be the partial pressure of H₂ at equilibrium? K_p = 10.1 at 400°C.
