Q. Which of the following slow down the reaction rate? (69th BPSC Prelims 2023)
(A) Catalytic promoter
(B) Homogenous catalyst
(C) Heterogeneous catalyst
(D) None of the above
Answer: C
Homogeneous catalysis because a catalyst is a substance that boosts the rate of a reaction but does not change chemically during the process
The reactants and catalyst are in the same phase in homogeneous catalysis (i.e., liquid or gas). The activity of the catalyst is reduced by the promoter.
A reaction inhibitor is a substance that decreases the rate of, or prevents, a chemical reaction. A reaction inhibitor is a substance that decreases the rate of, or prevents, a chemical reaction.
