Question 2(multiple choice worth 3 points) what happens to the rate of most reactions as the reaction progresses? the rate remains constant over the course of the reaction. the rate decreases as the concentration of the reactants decreases. the rate increases as the concentration of the products increases. the rate change depends on the energy change of the reaction.

-

The rate decreases as the concentration of the reactants decreases

Explanation: -

A reaction involves change of the reactants into products.

Initially there is only reactants. So the rate if reaction is high.

After some time there are products. So the amount of reactant is less.

Reactions involve collisions of reactant molecules. As the reactant amount decreases, collisions between the reactants decreases. As such the rate of reaction decreases with the progress of the reaction.
