Homework Statement


I have to list out some ways on how to determine the manganese content of a steel sample.

The Attempt at a Solution


I can only think of one right now, which is calorimetry...but I was wondering are there other simpler possible ways of determining it?
 
Physics news on Phys.org
X-ray fluorescence spectroscopy, SIM, RBS come to mind. Then there must be chemical methods.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
