Doubling Concentrations
Does doubling concentrations double the order of a reaction or does it just increase the order by 1?

Re: Doubling Concentrations
You can only find orders based on experimental data so this depends on the reaction. If you double the concentration and nothing happens to the rate, this is a zero order reaction. If you double the concentration and the rate also doubles, this is a first order reaction. If you double the concentration and the rate is squared this is a second order reaction.

Re: Doubling Concentrations
Changing the concentration in experiments can show you which order the reaction is, but it doesn't change the order of the reaction. In other words, in rate=k[A]^n, changing [A] does not change n.

Re: Doubling Concentrations
If you are talking about a first order reaction the doubling of a reactant means the reaction rate is doubled. If it's a second order reaction then the reaction rate is increase by a factor of x^2, where x would be your reaction rate.
