(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?
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.

Reduction of permanganate: A kinetics demonstration for general chemistrySteffel, Margaret J. Using the reduction of MnO4- to Mn2+ in aqueous solution to demonstrate the four factors that control reaction rates in solution: the natures of the reactants, concentrations of the reactants, temperature, and the presence of a catalyst. Steffel, Margaret J. J. Chem. Educ.1990, 67, 598.
