Question

Which action would speed up a chemical reaction in aqueous solution?

adding more powdered reactants




adding excess cold water




removing a catalyst




cooling the reaction mixture

Answer 1

adding excess cold water

Step-by-step explanation:

careful of the wrong answer above. the correct one is this.

Answer 2

adding more powdered reactants

Step-by-step explanation:

Powdered reactants talks about surface area of the reactant. Surface affects the rate of the reaction. So the larger the surface area, the faster the reaction.

From the question, adding more powered reactants will definitely speed up the rate of the reaction
