An order of 0 says the reaction rate is independent of the reactant concentration (s) I had a few questions, though. 1.) What exactly constitutes a negative order reaction if reaction orders are determined by the RDS in elementary steps? Are reactants being produced when the forward reaction occurs?
WebFeb 12, 2024 · The reason for this is because the reactants are decreasing as a function of time, the rate would come out to be negative (because it is the reverse rate). Therefore, putting a negative sign in front of the variable will allow for the solution to be a positive …
