Calculate k (T) given the following forms for the reactive cross section:
(a)бR(v) =πd2, ., a constant. If d is the molecular diameter, this represents an “encounter limited rate coefficient”.
(b)бR(E) =б0 ( 1 - e- a E )
Do any of these calculated k’s have an Arrhenius-like temperature dependence?
For a Lennard-Jones “ 6 - 12 ” potential determine the internuclear distance at the potential energy minimum.
The following reaction was done experimentally at various temperatures in order to obtain rate constants:
O + HO2 → OH + O2
T1 = 298 K k1 = x 10-11 cm3 / molecule·s
T1 = 229 K k2 = x 10-11 cm3 / molecule·s
Using the experimental data, find the activation energy Eact.
Calculate the following thermodynamic properties at T = 298 K using transition state theory: ΔE≠, ΔH≠, ΔS≠, ΔG≠.
The reaction of CH with N2 is of importance in the chemistry of ary atmospheres and hydrocarbon flames. By understanding the basic reaction, plex systems such bustion in the environment can be studied. The reaction is
CH + N2 →( CHN2 )≠→ HCN + N
Using transition state theory, find the partition functions for eac
