What is the primary factor that determines the rate of a chemical reaction?

The type of molecules that are combining

The activation energy required (correct)

The surface area of the solid reactants

The concentration of reactants

How does increasing the temperature affect the rate of a chemical reaction?

It decreases the activation energy, making the reaction faster

It decreases the concentration of the reactants, making the reaction slower

It has no effect on the rate of the reaction

It increases the kinetic energy of the reactant molecules, making the reaction faster (correct)

Which of the following factors would NOT increase the rate of a chemical reaction?

Increasing the surface area of solid reactants

Decreasing the activation energy with a catalyst (correct)

Increasing the pressure of the reactants

Increasing the concentration of the reactants
