Generalized BEP relations can be used to predict this quantity on metallic surfaces calculated via Marcus theory. Frustrated Lewis (10[1])pairs have higher values (-5[1])of this quantity (10[1])due to steric hindrance. (-5[1])This quantity (-5[1])is divided by R (10[1])in a plot of one-over-T (10[1])against (10[1]-5[1])the natural (10[1])logarithm of (10[1])k. (10[3]-5[2])The (10[1])high value of this (10[1])quantity (-5[1])in the Haber (10[1])process (10[1])is (10[1])due (10[1])to the (10[3])nitrogen (10[1])triple (10[2]-5[1])bond. (10[10]-5[1])This quantity (10[1]-5[1])is (10[1])divided (10[2]-5[1])by RT (10[5]-5[1])in the (10[1])exponential (10[6])of (10[1])the (10[1]-5[1])Arrhenius (10[2]-5[1])equation. (10[10]-5[7])This quantity (10[2])is determined (10[1])from the difference (10[1])between the transition state (10[3])and reactants (10[3])on a (10[1])reaction (10[1])coordinate diagram and can (-5[1])be lowered (10[1]-5[1])by catalysts. (10[6])For (10[1])10 (10[1])points, (10[5]-5[1])identify (10[2]-5[1])this quantity (10[1]0[1])denoted (10[2])E-sub-a, the minimum (10[2])energy (10[2])required (10[1])for a reaction (10[2])to (10[1])occur.
