A variation of this quantity is ideally maximized and minimized for “plug flow” and “continuous flow stirred tank” reactor configurations. Along with turnover frequency, reactor performance is often measured using the “space-time” form of this quantity. (-5[1])Exothermic reactors operate at a temperature that balances the tradeoff between rate and this quantity. For batch reactors, (10[1])this quantity equals the (-5[1])product of conversion and (10[1]-5[1])selectivity. (10[3])Green chemists use a variation (10[4])of this (10[1])quantity that accounts (10[1])for (10[1])byproducts (10[1])called (10[1])“atom (10[1])economy.” (10[5])In organic (10[1])chemistry labs, (10[2])failing to vaporize (10[1])any (-5[1])remaining solvent can make measurements (10[3])of this quantity (10[1])exceed (10[2])100 percent. (10[7]-5[3])For (10[1])10 points, (10[1])name this (10[1])quantity (10[3])that describes how much of (-5[1])a reactant (10[3])was converted into product. (10[1])■END■ (10[8])
