These questions require more thought and integrate several concepts.

Measurements of the initial rate of hydrolysis of benzenesulfonyl chloride in aqueous solution at 15 °C in the presence of fluoride ion yielded the results in the table for a fixed concentration of benzenesulfonyl chloride of 2 × 10^-4 M. The reaction rate is known to be proportional to the concentration of benzenesulfonyl chloride.

Note that some reaction must be occurring in the absence of any fluoride ion, because at zero concentration of fluoride the rate is not zero. This residual rate should be subtracted from each observed rate to give the rate of the reaction being studied.

(a) Derive the complete rate law for the reaction.

(b) Calculate the rate constant k and express it in appropriate units.
