2. A student determined the freezing point of pure t-butyl alcohol following the procedure given in this experiment. Because of an experimental error, the freezing point temperature that she obtained was higher than the correct value. Explain whether this error will lead to values of each of the following quantities that are larger or smaller than the correct values. (a) freezing point depression of the salicylic acid solution in t-butyl alcohol (b) molal freezing point depression constant of t-butyl alcohol
