Question

how can the rate of a reaction be increased? having a lower concentration of reactants having less surface area decreasing the amount of reactants increasing the temperature

Explanation:

• Lower concentration of reactants: Fewer reactant particles, less frequent collisions, slower reaction rate.
• Less surface area: Reduces contact between reactants, fewer collision opportunities, slower reaction.
• Decreasing amount of reactants: Fewer particles overall, less collision frequency, slower reaction.
• Increasing temperature: Increases kinetic energy of particles, more frequent and energetic collisions, faster reaction rate.

Answer:

increasing the temperature
