MCAT Chemical and Physical Foundations of Biological Systems Question of the Day

Test your knowledge with a hand-picked multiple-choice question.

If the reactants and/or products in a chemical reaction are gases, the reaction rate can be determined by measuring the change of pressure as the reaction proceeds. Consider the following reaction and pressure vs. reaction rate data below.

TrialPXY(torr)PZ(torr)Rate (torr/s)
11002000.16
22002000.32
32001000.04
42001500.14

If the volume of the container were reduced, what would happen to the rate of the reaction?
