Question

You have measured the rates of chemical reactions in two ways. You measured the rate of the productio of tion 7 a gas (o2) and you followed the consumption of dichromate ion spectrophotmetrically. Below are reactions. Design an experiment that allows you to you measure their rates? Be specific. A visibl spectrophotometer cannot be used for either one. tale cold measur the rate of the rxns Wong different Prems to manipulate tine temperatue we could use ice an h or we cad use a hot late And do af ram

Explanation / Answer

a) rate of reaction is given by law of mass action

i.e. Ka = (CH3CH2OH)(HBr) / (CH3CH2Br)

WATER IS TAKEN IN EXCESS QUANTITY. SO ITS CONCENTRATION CAN BE NEGLECTED..

b) Kb = (NOCl)2 / (NO)2 (Cl2)
