According to collision theory, why does increasing the temperature of a reaction mixture increase the rate of reaction?
Answer and explanation
Correct answer: B. Particles move faster
- Step 1: Higher temperature increases average kinetic energy (particles collide more frequently). Step 2. Crucially, it exponentially increases the proportion of particles whose collision energy exceeds the activation energy (E_a). Answer: Particles move faster. Why not the others: Only catalysts lower activation energy; temperature increases particle energy.
