In experiment P7 of the phys chem practicals the second order reaction between iodomethane and a hydroxide ion is studied The following measurements are performed to determine the rate constant k 8 3905 g of KOH and 9 7231 g of iodomethane are measured with an analytical balance a time of up to 3600 s is measured with a stopwatch a 100 ml volumetric flask with an accuracy of 0 2 ml and a 50 ml volumetric flask with an accuracy of 0 12 ml are used to prepare the reactants mixture and a burette with divisions of 0 1 ml and aliquots of up to 1 ml is used to determine the hydroxide ion concentration Calculate the minimum error due to stopwatch Select the correct answer 90 0014 0 00014 0 00037 0 0007
