Which outcome occurs when an industrial Sabatier reactor slowly loses catalyst activity?

A)Decreased methane production rates overall
B)Increased equilibrium constant favoring reactants
C)Higher selectivity for longer hydrocarbons
D)Faster establishment of chemical equilibrium

💡 Explanation

Decreased activity impacts kinetics; equilibrium will still be reached, but much slower. Poisoning reduces active sites on the catalyst, therefore the reaction rate constants decrease because fewer molecules can react per unit time, rather than altering equilibrium.
