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 (6)=15, what are the units of 6? What are the units of 15? What does this statement tell us about the reaction? The units of 6 are The units of 15 are f(6) 15 tells us (b) if (6) 3.what are the units of 6? What are the units of-3? What does this statement tell us? The units of 6 are The units of-3 are
