Need some help with a chemistry question: List three methods by which a change in concentration of a reactant or product can be determined.?
I know that one of the methods is Le Chatelier s Principle but what are the other two methods?

anonymous · Answer

one is from chemical kinetics" method of initial rates"

anonymous · Answer

let an reaction
r = k [A]a*[B]b
if you have two reaction as like r1 and r2, than
r1/r2 = {k [A]1a [B]1b}/{k [A]2a [B]2b}
by this you can predict concentration
