Question

How does a catalyst work to make a reaction go more quickly?

O A. It decreases the number of collisions.
O B. It raises the temperature of the reaction.
O c. It brings reactant molecules together.
O D. It increases the concentrations of the reactants.

Answer 1

C) It brings reactant molecules together.

Step-by-step explanation:

A.P.E.X

Answer 2

c. It brings reactant molecules together.

Step-by-step explanation:

Catalysts in chemical reactions works by bringing reactant molecules together thereby making the reaction proceed much faster.

A catalyst is any substance that speeds up the rate of chemical reactions. Sometimes, the activation energy of reactions are very great. This makes chemical reactions very difficult to proceed.

When a catalyst is introduced, they take the reactants and bring them close enough. This way, the activation barrier is lowered and the reaction can proceed.
