Question

Consider the following reaction:

H2O(g) + CO(g) H2(g) + CO2(g)

The equilibrium constant Kp for this reaction is 0.55 at 1023 K.

(i) In a reaction vessel, water vapour and carbon monoxide are introduced at a pressure of 3.50 atm, and allowed to reach equilibrium at 1023 K. Construct a table and use it to calculate the partial pressure of all the gases at equilibrium.

Answer 1

At equilibrium in the following reaction at room temperature, the partial pressures of the gases are found to be;

PN2 = 0.094 atm

PH2 = 0.039 atm

PNH3 = 0.003 atm.
