For question #37856 if the decomposition reaction is SECOND ORDER Reaction how do i use the second order law provided that its only its order that has changed not the other factors. please help am stuck.

The following reaction is important to produce a mixture known as ‘water gas’:

C (s)+H2O (g) ⇌ CO (g)+ H2 (g)

Suppose 0.100 mol of H2O and solid carbon, together with 7.16 atm. of CO and 8.17 atm. of H2, are placed in a 1.00 dm3 reactor at 800°C. The value of Kp is 14.1 under these conditions.

Use the ideal gas law to determine the partial pressures of all the species at the start, and then determine the concentrations of all the species at equilibrium.
