HALOGENATION OF PROPANONE
Hint
In the Halogenation of Propanone example, the state state species is eliminated from the expression for the overall rate of consumption of iodine, by replacing [Pe] wherever it appears in the
-d[I2]/dt = + k2[I2][Pe]equation, with
+ k1[H+][Pk] / (k-1[H+] + k2[I2])
Eliminating the Steady State Species from the Expression for the Overall Rate of Consumption of Iodine
The derived equation for the steady state concentration of the enol form of propanone
[Pe]ss = + k1[H+][Pk] / (k-1[H+] + k2[I2])can now be back-substituted into the expression for the overall rate of consumption of iodine
-d[I2]/dt = + k2[Pe][I2]in order to eliminate [Pe] from this equation.
This results in
-d[I2]/dt = + k1[H+][Pk] / (k-1[H+] + k2[I2])
