The higher the concentration and the hotter the temperature, the more pronounced the chlorine degradation was.

The decomposition can be stated in this following equation: 2 ClO- (aq) –> 2 Cl- (aq) + O2 (g) To measure the rate of decomposition, a catalyst is needed to fasten the reaction. A suitable catalyst is Co2O3, which is produced from mixing Co (NO3)2 and bleach.

WebLooking at the rate constants and the volume of bleach one can work out the order the reaction with respect to the bleach. If the reaction is first order with respect to the bleach, then doubling the volume of the bleach will double the rate constant. From the group data table above you can see this does in fact happen, e.g. Group 1 and Group 3.
