Rate of a chemical reaction is not influenced by the__________________?
Correct answer: D. Number of molecules of reactants taking part in a reaction
- A. Catalyst
- B. Temperature
- C. Reactants concentration
- D. Number of molecules of reactants taking part in a reaction
Explanation
Reaction rate is directly affected by temperature, reactant concentration and catalysts, but the mere number of molecules shown in the reaction equation is not an independent rate factor. Molecularity describes an elementary step, not a general operating variable controlling rate.
