Question

what procedure could you use to test the effect of a catalyst on a reaction? add the catalyst to the reactants and then increase the temperature until the reaction occurs. combine the reactants and the catalyst to see how long it takes them to react. combine the reactants; when they begin to react, add the catalyst to stop the reaction. observe the rate of the reaction and then observe it again with the catalyst included.

Answer 1

Answer: observe the rate of the reaction and then observe it again with the catalyst included.

Step-by-step explanation:

Rate of the reaction is determined by how fast reactants change into products.

The reactants must possess a minimum amount of energy called as activation energy to cross the energy barrier and convert to products.

A catalyst is a substance which when added to a chemical reaction, increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products. The catalyst thus increases the rate of reaction.
