According to collision theory, why does increasing the concentration of reactants increase the reaction rate?

  1. It lowers the activation energy.
  2. It increases the average kinetic energy of the particles.
  3. It increases the frequency of collisions between particles.
  4. It shifts the equilibrium to the products.

📝 Batafsil tushuntirish

Higher concentration means more particles per unit volume, which leads to a higher probability and frequency of collisions per second.
