A: Activation energy is the minimum amount of energy required for a chemical reaction to occur.

3. What is a reaction mechanism?
A: A reaction mechanism is a step-by-step description of the pathway by which a chemical reaction occurs.

VIII. Thermochemistry
1. What is heat?
A: Heat is a form of energy that is transferred between two objects due to a temperature difference.

2. What is Hess's law?
A: Hess's law states that the overall enthalpy change in a chemical reaction is independent of the pathway taken.

3. Define calorimetry.
A: Calorimetry is the measurement of heat transfer in a chemical reaction or physical process.

IX. Electrochemistry
1. What is a redox reaction?
A: A redox reaction is a type of chemical reaction in which electrons are transferred between species.

2. What is an electrolytic cell?
A: An electrolytic cell is a type of electrochemical cell in which electrical energy is used to drive a non-spontaneous chemical reaction.

3. What is a galvanic cell?
A: A galvanic cell is a type of electrochemical cell in which a spontaneous chemical reaction generates an electrical current.

X. Organic Chemistry
1. What is an organic compound?
A: An organic compound is a compound that contains carbon atoms bonded to hydrogen atoms, and often other elements such as oxygen, nitrogen, or sulfur.

2. What are functional groups?
A: Functional groups are specific atoms or groups of atoms within a molecule that determine its chemical properties and reactivity.

3. What is isomerism?
A: Isomerism is the phenomenon in which two or more compounds have the same chemical formula but different structural arrangements.
