Question

34.All of the following procedures can be expected to increase the rate of a chemical reaction except...Select one:a. changed the temperature of the reaction.b. decreasing the concentration of the reactants. c. increasing the surface area of the reactants.d. introducing a catalyst into the reaction.

Answer 1

b. decreasing the concentration of the reactants.

Step-by-step explanation

Procedures which is expected to increase the rate of a chemical reaction are:

i. Changed the temperature of the reaction.

ii. Increasing the concentration of the reactants.

iii. Increasing the surface area of the reactants.

iv. Introducing a catalyst into the reaction.

Therefore, the only option which will not increase the rate of a chemical reaction is:

b. decreasing the concentration of the reactants.
