Chemical Kinetics Effect of Concentration on First-Order Reaction

20

Choose the best answer

A gaseous reaction is experimentally first order overall. If the vessel volume is reduced to one-third at constant temperature, the reactant concentration becomes three times larger. The reaction rate therefore becomes:
