Zero Order Reaction Example

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

Zero Order Reaction Example

I don't really understand what a zero order reaction is. Can someone explain what it is and give an example of one?

Re: Zero Order Reaction Example

A zero order reaction is a reaction in which the rate is independent of the concentration of reactants. This means that the rate law of a zero order reaction is rate = k. I believe the reaction 2NH3 (g) --> N2 (g) + 3H2 (g) is a zero order reaction because the rate does not depend on the concentration of ammonia.

Re: Zero Order Reaction Example

A zero order reaction is one where changing the concentration of your reactants does not change the initial rate of the reaction, meaning that your reaction rate is independant of that reactant. Zero order reaction K values will have M/s units.
