Which of the following factors does NOT affect the rate of a chemical reaction?

The presence of a catalyst
Temperature
Concentration of reactants
Surface area of reactants
Type of vessel holding the reactants

Answer: Type of vessel holding the reactants

Chemical reactions occur when colliding molecules have the correct orientation and energy. The type of vessel holding the reactants does not affect either of these factors, and thus does not affect the rate of a chemical reaction.
