Take the data from the previous exercise and test for first order by carrying out an exponential fit using Excel. Find the value of the rate constant.

Previous Exercise

The following is a set of data for the following reaction at 25 ^◦C.

(CH₃)₃CBr + H₂O → (CH₃)₃COH + HBr.

Using linear least squares, determine whether the reaction obeys first-order, second-order, or third-order kinetics and find the value of the rate constant.
