Which condition will increase the rate of reaction?
Correct answer: D. Increase in temperature and increase in concentration of reactants
- A. Decrease in temperature and concentration of reactants
- B. Decrease in temperature and increase in concentration of reactants
- C. Increase in temperature and decrease in concentration of reactants
- D. Increase in temperature and increase in concentration of reactants
Explanation
Option d is correct. Both increasing temperature and concentration of reactants lead to an increase in the rate of reaction. Higher temperature provides more kinetic energy to the molecules, leading to more frequent and energetic collisions. Higher concentration means more reactant particles, which increases the chances of collision.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
