Zero order reaction

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

Zero order reaction

How do we determine if a reactant is zero order?

Re: Zero order reaction

It is zero order if its concentration has no effect on the rate.

Re: Zero order reaction

For instance, a liquid or solid would not affect the rate

Re: Zero order reaction

You can tell if the concentration doesn’t affect the rate at all. Also the k will be a negative slope.

Re: Zero order reaction

The graph of a zero order reaction will be [A] vs. time and will have a slope of -K

Re: Zero order reaction

It will not affect the rate of reaction.

Re: Zero order reaction

You can derive the integrated rate law from -d[A]/dt= k bc and see that the rate is independent of concentration.

Re: Zero order reaction

You can determine experimentally, when observing that the initial rates don't change when changing the concentration of the reactants, or by looking at your K units as your K would have to be in the units of M/s to offset the unitless reactant.
