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