Answer:
K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]
Step-by-step explanation:
Based on the reactions:
CH2 (g) + H2O(g) ⇄ CO (g) + 3H2 (g) K1
CO (g) + H2O (g) ⇄ CO2 (g)+H2(g) K2
The sum of both reactions is:
CH4 (g)+2H2O (g) ⇄ CO2(g)+4H2(g) And K of the reaction is: K = K1×K2
K is defined as the ratio between concentrations of products and reactans. Each compound must be elevated to its coefficient in the reaction. That is:
K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]
