The energy needed to start a chemical reaction is called (1) potential energy (2) kinetic energy (3) activation energy (4) ionization energy

Step 1: Define the Problem

Identify the correct term for the energy required to initiate a chemical reaction.

Step 2: Break Down the Problem

Examine each option to determine which one accurately describes the energy needed to start a chemical reaction.

Step 3: Apply Relevant Concepts

• Potential Energy: Energy stored in an object due to its position or configuration.
• Kinetic Energy: Energy of an object due to its motion.
• Activation Energy: The minimum energy required to initiate a chemical reaction.
• Ionization Energy: The energy required to remove an electron from an atom or molecule.

Step 4: Analysis, Verify and Summarize

The energy needed to start a chemical reaction is specifically the energy barrier that must be overcome for reactants to transform into products. This is known as activation energy.

Final Answer

The energy needed to start a chemical reaction is called (3) activation energy.
