Question

Which statement below is true only for a homogeneous catalysts?

a. A homogeneous catalyst increase the rate of reaction by providing an alternative pathway with a lower activation energy.

b. A homogeneous catalyst is a solid substance to which liquid or gaseous reactants will adhere to the surface of the catalyst.

c. A homogeneous catalyst is when the catalyst is in the same physical state as the reactant.

d. A homogeneous catalyst will eventually be consumed in a chemical reaction.

Answer 1

Answer - c

Homogeneous catalysts means physical state of reactants and catalyst is same .

2SO₂ (g) +  O2(g) ------------------->  2SO_3(g) catalyst ---- NO (g)

in this reaction reactant and catalyst present in only gaseous state
