State the detailed mechanism of the reaction of benzene with isopropanol in sulfuric acid.
Do not apply the calculations, based on the approximation of the stationary state, to make them perform correctly. Basta discard
the 3 responses that you encounter that are obviously erroneous if you apply the formula to determine the speed of a reaction.
For the decomposition reaction of N2O5(g): 2 N2O5(g) · 4 NO2(g) + O2(g), the following mechanism has been proposed:
N2O5
-> NO2 + NO3_(K1)
NO2 + NO3 →> N2O5 (k-1)
→
NO2 + NO3
→
NO2 + O2 + NO (K2)
NO + N2O5
→ NO2 + NO2 + NO2 (K3)
Give the expression for the acceptable rate.
