1. Identify 2 possible sources of error. Explain
how that source of error could effect your data.
For example: If the bottle of acetone was left
without the lid on for a long period of time, some of
the acetone could evaporate. This would decrease
the actual concentration of acetone in the bottle,
while students still assume its 4.0 M. Because the
true concentration of acetone would be lower, it
could possibly slow down their reaction rate and
effect their calculated rate. (Because I explained
how concentration would effect the rate - you
cannot discuss the effect of evaporated reagents -
you cannot say if the concentration of iodine or HCI
was lower than the true value!)
