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