The rate law of a reaction, A-> B+C is given by the expression: Rate=k, where k=0.0113 mol/L min. If the initial concentration of the reactant is 0.225 mol/L, how long does it take for the concentration to decrease to 0.180 mol/L?

I know i have to find the order of the reaction to use the right integrated rate equation but how do i get the order of the reaction?

• Chemistry -

If rate = k, isn't that a zero order reaction?

• Chemistry -

Yes in fact it is. So does that mean that the time it takes for the concentration to decrease to 0.180 mol/l would just be k then since its a zero order?
