All those factors that change the _ affect rate of reaction.
Correct answer: D. Effective collisions per second
- A. Polarity of molecules
- B. Velocity constant
- C. Rate constant
- D. Effective collisions per second
Explanation
Effective collision per second affects the rate of reaction as it determines the number of reactant molecules having enough energy to react and how many of those collisions are successful. The more effective collisions per second, the higher the rate of reaction. Factors like concentration, temperature, pressure, surface area and the presence of catalyst can influence the frequency and effectiveness of these collisions, thereby affecting the rate of reaction.

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.
