I am looking for the time for a chemical reaction, T (in minutes), is a function of the amount of the catalyst present, T= f(a)

The time for a chemical reaction, 7" (in minutes), is a function of the amount of catalyst present, a (in milliliters), so T = f (a). (a) If f(9) = 15, what are the units of 9? What are the units of 15? What does this statement tell us about the reaction? The units of 9 are The units of 15 are f(9) = 15 tells us (b) If f'(9) = -6, what are the units of 9? What are the units of -6? What does this statement tell us? The units of 9 are The units of -6 are v f'(9) = -6 tells us V Click if you would like to Show Work for this question: Open Show Work
