Answer:
Add a lot of water to the reaction mixture.
Explanation:
The rate of the reaction is directly proportional to the concentration of the reactants.
So, adding a lot of water to the reaction mixture will decrease the concentration of the reactants. Thus, it slows down or stop the reaction.
- Pressure has no effect on the reaction since the reactants and products are in aqueous phase.
- Increasing the surface area of the reactants will increase the rate of the reaction.
- Add a catalyst to the reaction mixture will increase the rate of the reaction since it lowers the activation energy required to initiate the reaction.
So, the right choice is:
add a catalyst to the reaction mixture
