Reaction Kinetic Labs

Trang Nguyen testing ground Report Chemistry 162: Reaction Kinetics Lab The purpose of this examine: In this experiment, students aim to mark off the treasure law of the reception by finding the time for all(prenominal) trial of diametric runs occurring. Upon studying initial reaction evaluate at vary reactant concentration, students will give break through closing about the put of the concentration towards the reaction rate. Next, the effect of the surface ion catalyst on the reaction rate will be studied by adding a dilute Cu(NO3)2 to the reaction. Finally, students will determine the effect of temperature on the reaction rate by carrying out the reaction at different hot and temperature, then number the activation energy.
