Imagine you run a reaction whose free energy of activation (AG*) is 18 kcal/mol. If it were a first
order reaction, its' half life (the time for half the starting material to go away) or half the product to
form (assuming a 100% yield) would by In2/k where k is the rate constant. How long will it take for
the reaction to be done if you run the reaction in an ice-salt bath at room temperature (20 °C) if the
rate constant were 1x 10-4/sec?
