Problem 14-14

Aluminum forms a I: I complex with 2-hydroxy-lnaphthaldehyde p-methoxyhenzovlhvdraxonal.which absorbs UV radiation at 285 nm. Under pseudo-firstorder~o~ditions, a plot of the initial rate of the reaction (absorbance units persecond) versus the concentration of aluminum (in J.lM)yields a straight line describedby the equationrate = 1.74c" - 0.225Find the concentration of aluminum in a solution that exhibits a rate of 0.76 absorbanceunits per second under the same experimental conditions.
