Consider a bimolecular reaction in the gas phase.Which one of the following changes in condition will not cause an increase in the rate of the reaction?

Question

Quizplus · Accepted Answer

Increasing the volume at constant temperature will not increase the rate of the reaction because the concentration of the reactants will decrease proportionally to the increase in volume, leading to fewer collisions and lower reaction rates. The other options, adding a catalyst and increasing the temperature, will both increase the rate of the reaction by providing more effective collisions between the reactant molecules. Therefore, option C is the only valid answer.
