RRKM theory predicts that this quantity is equal to [read slowly] degeneracy times the sum of states over h times the parent ion density of states. The Gillespie algorithm models reactions by sampling from the system’s probability distribution of this quantity. This quantity appears in the numerator of the first Damköhler number. The reciprocal of this quantity is graphed on the y-axis of a Lineweaver-Burk plot. This quantity (15[1])decreases (-5[1])when substituting deuterium for (15[1])hydrogen in the (*) kinetic isotope effect.. This quantity equals the [read slowly] pre-exponential factor times e to the negative E-sub-a over RT according to the Arrhenius equation. By definition, concentration does not affect this quantity for (10[1])zeroth-order reactions. For 10 points, name this quantity that measures how quickly a reaction proceeds. (10[1])■END■
