1. What is activation energy?
The energy released during a chemical reaction.
The minimum energy required to start a chemical reaction.
The energy stored in the chemical bonds of reactants.
The energy of the products after a reaction.
2. How does a catalyst affect activation energy?
It increases activation energy.
It decreases activation energy.
It has no effect on activation energy.
It changes the products of the reaction.
3. The transition state, also known as the complex, is a high-energy intermediate state between reactants and products.
4. In an exothermic reaction, the products have energy than the reactants.
5. Enzymes are biological that speed up biochemical reactions by lowering the activation energy.
6. Explain why increasing the temperature generally increases the rate of a chemical reaction, in terms of activation energy.
7. A reaction with a high activation energy will proceed faster than a reaction with a low activation energy, assuming all other factors are equal.
