Question

Hydrogen is manufactured on an industrial scale by this sequence of reactions: CH2 (g) + H2O(g)=CO (g) + 3H2 (g) K1 CO (g) + H2O (g)=CO2 (g)+H2(g) K2The net reaction is:________ CH4 (g)+2H20 (g)=C02(g)+4H2 (g) KWrite an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K1 and K2. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator K = _______

Answer 1

Answer:

K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]

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]
