what factors affect the rate of a chemical reaction?
Answer
Brief Explanations:
Several factors impact reaction rates. Concentration of reactants: more particles increase collision frequency. Temperature: higher - temp gives more kinetic energy. Surface area: greater surface area exposes more reactant particles. Catalysts: lower activation energy.
Answer:
Concentration of reactants, temperature, surface area, and presence of catalysts.
