WebThe first step of H2O2 with I- (iodide not iodine) to make H2O and IO- is the rate limiting step making the rate law: rate=k [H2O2] [I-]. First order in the reactant and first order in the catalyst and second order overall. 2 I -> I2 + 2 H2O, that's a little trickier. It's multi-step, and I don't really know what the rate law is. Webproduct with time. We choose the iodine to monitor because it is a colored solution which can be seen. When this reaction is run by itself, a yellow/brown color will slowly appear as iodine is produced. You will do this by using a second reaction, referred to as a “clock” reaction. The clock reaction indicates when a specific amount of I 2

The overall redox reaction is shown below. ( 4 ) S 2 O 82− ( aq) + 2 I − ( aq) → I 2 ( aq) + 2 SO 42− ( aq) The rate law can be written as follows. ( 5 ) crt full form computer
