Question

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 balance.
Select the correct answer.
