10 Questions
What is the primary purpose of activation energy in a chemical reaction?
To provide enough energy to break chemical bonds and start the reaction
How does the activation energy level relate to the overall energy change of a reaction?
The activation energy level must be lower than the overall energy change
In an exothermic reaction, what is the relationship between the activation energy and the energy released by the reaction?
The activation energy is less than the energy released
How does increasing the concentration of reactants affect the rate of a chemical reaction?
Increasing concentration increases the rate of reaction
What is the role of a catalyst in a chemical reaction?
A catalyst decreases the activation energy required for the reaction
How does increasing the surface area of the reactants affect the rate of a chemical reaction?
Increasing surface area increases the rate of reaction
What is the role of temperature in a chemical reaction?
Increasing temperature decreases the activation energy required for the reaction
How do inhibitors affect the rate of a chemical reaction?
Inhibitors decrease the rate of reaction by increasing the activation energy
What is the relationship between the activation energy and the energy change of a reaction?
The activation energy is always greater than the energy change of the reaction
How does the presence of a catalyst affect the activation energy of a chemical reaction?
The catalyst decreases the activation energy required for the reaction
