Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z

The Potato Epidemic One fine morning in the Kingdom of Sandwiches‚ SandwichKing and Sandwich‚ his pet‚ were going for a walk. Suddenly‚ green potatoes‚ “The SWAT‚” came out of nowhere and asked a million questions about mashed potatoes? Then suddenly‚ as fast as they had appeared‚ they disappeared. “Who was that?” asked SandwichKing‚ “And what do they want with mashed potatoes? Whatever.” Then SandwichKing and Sandwich continued on their walk. The next day‚ when SandwichKing looked out his window

first tested the effect of temperature on enzyme activity. The independent variable in the first experiment was the temperature of the solution of pH 7 buffer‚ potato juice‚ and the enzyme. The independent variable for the second experiment was the pH of the phosphate buffer. The independent variable for the third experiment was the enzyme concentration of the solution‚ and finally the independent variable of the fourth experiment was the substrate concentration. For all four experiments‚ the dependent

Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the
