Collision Theory

Q1: What is collision theory?

A reaction occurs when particles collide with proper orientation and enough energy.

Q2: What three conditions are required for a successful reaction?

Collision, correct orientation, and energy ≥ activation energy.

Q3: What is activation energy (Ea)?

Minimum energy needed to start a reaction.

Q4: What does kinetic theory state about matter?

All matter is made of particles in constant, random motion.

Q5: What type of collisions does kinetic theory describe?

Elastic collisions (no loss of kinetic energy).

Q6: What causes particles to collide more frequently?

Higher temperature, concentration, or kinetic energy.

Q7: What determines whether a collision is successful?

Proper alignment and sufficient energy.

Q8: What happens if energy is less than Ea?

No reaction occurs.
