All of the following factors affect rate of reaction EXCEPT:
Correct answer: B. Molecularity
- A. Concentration of reactants
- B. Molecularity
- C. Catalyst
- D. Temperature
Explanation
Molecularity refers to the number of molecules or ions that participate as reactants in an elementary reaction step. While molecularity is important for understanding reaction mechanisms, it doesn't directly impact the overall reaction rate. The rate of a reaction is determined by factors like reactant concentrations, temperature, and the presence of catalysts.

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.
