Rate law problem for a reaction?

can someone help me with this problem? Consider the following reaction: 2O3 (g) --> 3O2 (g) and the rate law for the reaction is as follows: Rate= k [O3]^2/ [O2] suppose that a 1.0L reaction vessel initially contains 1.0 mol of O3 and 1.0 mol of O2. what fraction of the O3 will... show more can someone help me with this problem?

Consider the following reaction:
2O3 (g) --> 3O2 (g) and the rate law for the reaction is as follows:

Rate= k [O3]^2/ [O2]
suppose that a 1.0L reaction vessel initially contains 1.0 mol of O3 and 1.0 mol of O2.

what fraction of the O3 will have reacted when the rate falls to one-half of its initial value?
