I was reading the "Equilibrium reactions or opposed reactions" sections of:  http://en.wikipedia.org/wiki/Rate_equation

This section produces a rate equation dependant on the stoichiometric coefficients of the reactants.  Can someone please explain why this is the case - I was under the impression that the rate equation is independant of the stoichiometric coefficients.

Thanks

according to rate law,
reaction rate=k

• ^m[y]ⁿ
  rate equation is independant of the stoichiometric coefficients.
  this only holds true if the reaction is not elementary step.
