Chemistry The time required for a certain chemical reaction is Catalyst and Reaction Time related to the amount of catalyst present during the reaction. The domain of the relation is the number of grains of catalyst, and the Number of Number of range is the number of seconds required for a fixed amount of the Grains Seconds chemical to react. The table shows the data from several reactions. 2.0 180 a. Is the relation a function? 2.5 6 b. If the domain and range were interchanged, would the relation 2.7 0.05 be a function?
