The rate of the reaction can be written in three ways:
The relationship between k and k' and between k and k" are:
k'=2k k'=k
k'=2k ; k"=k/2
k'=2k ; k"=2k
k'=k ; k"=k
As we learned in
Rates in presence of stoichiometry of reactants/products -
When stoichiometry coefficients of reactants/ products are not equal to one, the rate of disappearance of & the rate of appearance of products is divided by their respective stoichiometric coefficients
- wherein
Option 1)
k'=2k k'=k
incorrect
Option 2)
k'=2k ; k"=k/2
correct
Option 3)
k'=2k ; k"=2k
incorrect
Option 4)
k'=k ; k"=k
incorrect
