How do you find rate of production of Cl? If you are given the inital rate to be 3.54e-5 and given measured data of .052[HgCl2] and .300[C204]? The equation is 2HgCl2(aq)+ C204(aq) goes to 2Cl+ 2Co2(g)+ Hg2Cl2(s). I thought that you may take the initial rate divided by the coefficent of Cl, but i'm not sure.
