Question: The time for a chemical reaction, T (in minutes), is a function of the amount of catalyst present, a (in milliliters), so T = f(a).
(a) If f(5) = 18, what are the units of 5? What are the units of 18? What does this statement tell us about the reaction?
(b) If f'(5) = -3, what are the units of 5? What are the units of -3? What does this statement tell us?
