What is the term used for the minimum kinetic energy required for the reactant molecules to undergo reaction?
What is the term used for the minimum kinetic energy required for the reactant molecules to undergo reaction?
Show Hint
The minimum energy that reactants must have to react is the activation energy.
Updated On: Oct 1, 2026
- Potential energy
- Bond energy
- Thermal energy
- Activation energy
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Colliding molecules react only if they carry at least a certain minimum energy. That threshold is the activation energy \(E_a\).
Step 2: Detailed Explanation
Activation energy is the minimum energy the reactant molecules must have to cross the energy barrier and form products.
Potential energy and thermal energy are general forms of energy, and bond energy is the energy to break a bond. None of these names the threshold for reaction.
Final Answer:
The term is activation energy, option (D). \[ \boxed{\text{Activation energy (D)}} \]
