Rico is doing an experiment. He makes a solution of calcium carbonate in a beaker of 200 mL of water at room temperature (25 °C). He adds a small amount of lemon juice to the solution
and a chemical reaction begins. Rico reduces the temperature of the solution by 10 °C by
adding ice. As the solution cools, what will happen to the chemical reaction?
The chemical reaction will stop suddenly.
There will no change in the rate of the chemical reaction.
The chemical reaction will slow as the water cools.
The speed of the chemical reaction will increase as the water cools.
