Use the References to access important values if needed for this question. For the gas phase isomerization of methyl cis-cinnamate, cis-C6H5 CH=CHCOOCH3 → trans-C6H5 CH=CHCOOCH3 the rate constant at 669 K is 9.12 x 10-4 s and the rate constant at 711 Kis 5.79 x 107 s-¹. -3 The activation energy for the gas phase isomerization of methyl cis-cinnamate is kJ.
The free energy change, AG, in the homogenous cross-exchange ET reaction of [Ru(bpy)2]* and ferricytochrome c is -104.6 kJ mol¯1. The second-order activation-limited rate constant, kobs, is 2.5 × 108 M-1 s-1. Taking KDA = 1.0 M¹, N = 1 × 1011 s-1, and x = 1, estimate the values of AG* and 2. In what kinetic region is this reaction? Hint: By substituting the Marcus equation into the expression for the rate constant of an adiabatic homogenous ET reaction, the rate constant of a cross-exchange ET reaction may be written as (AG+2)² Ket = KVN exp - 4λRT and, by rearrangement, In Ket KV 1 (AG+ 2)² 1 AG2 1 AG == + constant 42 RT 42 RT 2 RT
