<span>A Homogeneous Catalyst exists in the same physical state as that of the reaction it catalyzes.

Explanation:
                     
Catalysts are classifies as follow,
                                                      1. Homogeneous Catalyst
                                                      2. Heterogeneous Catalyst

</span>Homogeneous Catalyst are those which are in same phase as that of reactants are.

Example:

         Acetic Acid + Ethanol + H₂SO₄  →  Ethyl Acetate + H₂O + H₂SO₄

In this reaction catalyst and reactants all are in same phase i.e. Liquids.

Heterogeneous Catalyst are those which are in different phase as that of reactants are.

Example:

                                 Ethene + H₂ + Ni  →  Ethane + Ni

In this reaction ethene and hydrogen are gases while Nickle catalyst is in solid state.

Which of the following statements is (are) true about enzyme-catalyzed reactions? a. The reaction is faster than the same reacti
Brums [2.3K]

Answer : The correct option is A.

Explanation :

Enzyme-catalyzed reaction :

Enzyme act as a biological catalyst and the role of catalyst is to increase the rate of chemical reaction by lowering the activation energy.

Most of the chemical reactions are slow in the absence of enzyme but in the presence of enzyme, the reaction become faster. That means the Enzyme accelerate the rate of reaction.

Therefore, the correct answer is the reaction is faster than the same reaction in the absence of the enzyme.
