Question

A reaction is shown below.

What can be concluded about this reaction?

a. A homogeneous catalyst is being used in the reaction.
b. A heterogeneous catalyst is being used in the reaction.
c. A catalyst is not being used in this reaction.
d. An enzyme is being used in this reaction.

Answer 1

B

Step-by-step explanation:

I took the test

Answer 2

I think it would be B "A heterogeneous catalyst is being used in the reaction"

This is because MnO2 is a heterogeneous catalyst as it's in a different state than the rest of the reactants and products.
The MnO2 isn't being used as a reactant so it's a catalyst.
MnO2 is not an enzyme
