<u><em>Answer:</em></u>
Correct option is D.
It accelerates the reaction rates of a mixture.
<u><em>Explanation:</em></u>
It is used to speed up a reaction by lowering the activation energy.Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products.
<u><em>Types</em></u>
There are two types of catalyst (1) Homogeneous (2) Heterogeneous
In a heterogeneous reaction, the catalyst is in a different phase from the reactants. In a homogeneous reaction, the catalyst is in the same phase as the reactants.
A change of state (which is a physical change) can cause gas.
