Unformatted text preview: Time (sec) [C4H9Cl] 100 .082 400 .045 Average rate= - (final initial / time final time initial) = .00012 M/s Instantaneous Rate= slope (or tangent) of kinetic curve at a specific time point Example: determine instantaneous rate at t= 600s Choose any two points on the tangent (initial and final, preferably spread apart) initial (400s, .042) final (800s, .018) rate= - (.018 M - .042M / 800s 400s) .00006 M/s Initial rate- tangent to slope at t=0 = .0002 note: reaction rates decrease with time Rates can be written in terms of any reactant or product (as long as you use minus signs for reactants to make sure the rate of reaction is positive)...
