Which phrase describes a homogeneous catalyst?

Apresent in many biological reactions
Bused to detoxify exhaust gas
Cexists in a different phase than the reactants
Dwork best in high temperatures

Verified Answer :

the phrase that best describes a homogeneous catalyst is : A. Present in many biological reactions
since in a homogeneous catalyst the catalyst is in the same phase as the reactant, it  applies in both gas and solid phase

hope this helps

Answer: Option (A) is the correct answer.

Explanation:

When both reactants and catalyst are present in the same phase then it is known as a homogeneous catalyst.

Catalysts help in increasing the rate of a chemical reaction without itself getting consumed as catalysts lowers the activation energy path. Therefore, molecules with less energy can also effectively take part in the reaction.

Catalysts also help in carrying out various biological reactions.

Thus, we can conclude that the phrase present in many biological reactions describes a homogeneous catalyst.
