1. Introduction
In this experiment, we measured the rate of chemical reaction by using Iodine clock. And we observed how reactant concentration, catalysts, and temperature affect the rate of a chemical reaction. For this, we should understand rate equation and determined the orders of reaction.
2. Experimental
Prepared 5 kinds of solution by using 20mL vial.
1st - 5mL of ,( 5mL of 0.2 M KI ) and 5mL of 0.1M K2S2O8 at room temperature
2nd - 5mL of ,( 2.5mL of 0.2 M KI ), 2.5mL of 0.2M KCl and 5mL of 0.1M K2S2O8, at room temperature
3rd - 5mL of ,( 5mL of 0.2 M KI ), 5mL of 0.1M K2S2O8 and 2.5mL of K2SO4 at room temperature
4th - 5mL of , ( 5mL of 0.2 M KI ) and 5mL of 0.1M K2S2O8 at room temperature
5th - 5mL of , (5mL of 0.2 M KI ) and 5mL of 0.1M K2S2O8 at 10℃
(we added the KI solution the last)
And we stirred well by magnetic bar and added the KI solution each vial.
Measure the time immediately after …(To be continued )
