(1) Based on the units of the rate constant, what is the order of the reaction? {1:MULTICHOICE:zero-order#No, that is not correct.~=first-order#Correct!~second-order#No, that is not correct.~third-order#No, that is not correct.}
(2) What is the concentration of CH3CN after 0.20 minutes of reaction if the initial concentration is 0.10 M? {1:NUMERICAL:=4e-4:1e-5#Correct!~%50%4e-4:5e-5#Close, but not quite.}(Do not include units!)

Rate Law
Kinetics : RateLawChangeConc (10 Variations) The rate law for a reaction is rate=k[A][B]. If the concentration of A doubles, the rate of the reaction will do which of the following?
Experiments with AspirinLonda L. Borer and Edward Barry Experiments include (i) synthesis, purification, and characterization of aspirin by mp and TLC, (ii) percentage composition of a commercial aspirin tablet by titration, (iii) kinetics of the hydrolysis of aspirin to salicylic acid under various conditions, (iv) synthesis and characterization of copper(II) aspirinate and copper(II) salicylate, and (v) reaction of copper(II) aspirinate in aqueous solution.

Chemistry Time: Factors Affecting the Rate of a Chemical Reaction This activity can be used to introduce a unit on chemical kinetics, but it is simple enough to be used in a discussion of chemical reactions or experimental methods/procedures during the first weeks of the semester. The activity involves reacting bicarbonate with acid, a reaction with practical applications in everyday life. J. Chem. Educ.1998, 75, 1120A.

Audience-Appropriate Analogies: Collision TheoryKent W. Piepgrass This article presents two new analogies for collision theory based on arcade games and on the interactions between salesclerks and customers in a store. The uses, limitations, and possible extensions of the analogies are discussed. Piepgrass, Kent W. J. Chem. Educ.1998, 75, 724.
