Expert Solution
Step 1

Given that - 

Following balanced chemical reaction - 

CH4(g) + O2(g) <----> C(s) + 2H2O(g) 

 

Then, from law of equilibrium - 

Rate constant = concentration of products/concentration of reactants 

K = [C][H2O]2/[CH4][O2] 

But solid state of the substance can not be used due to its constant concentration. This it can be written as - 

K = [H2O]2/[CH4][O2]
