Stoichiometric Coefficients

Postby RuchaDeshpande1L » Thu Mar 08, 2018 11:57 pm

For the method of initial rates, do the stoichiometric coefficients of the balanced reaction equation matter in determining k or n?

It sorta depends on the problem, I guess, depending on what information you're given from the start. As long as you adjust your reactant concentrations accordingly, you should be fine.
For example, if A -> 2B and they ask you to find k, given initial [A] and final [A], you don't really need to mind the 2 in front of the B. However, if they give you the initial [A] and the final [B], you'll need to multiply accordingly.

Only the given experimental data should be taken into account when determining k and n with initial rates, and the coefficients should not play a role at all
