At 300 K the reaction below obeys the rate law Rate=k[NOCl]^2, where k=2.8 X .000010 M to the neg 1 times s to the neg 1.

2 NOCl >>>>>> 2NO + Cl2

Suppose 1.0 mole of NOCl is introduced into a 2.0-liter container at 300 K. Evaluate the half-life of the reaction.

#### Solution Preview

From the rat law, you should recognize that the reaction is of second order. We need to use the 2nd order integrated rate equation....

kt = 1/[A]t - ...

#### Solution Summary

It finds the half-life of the reaction given the rate law of the reaction.
