Introduction

Thereaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example, the oxidationof iron under the atmosphere is a slow reaction that can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second.
Chemical kinetics is the partof physical chemistry that studies reaction rates. The concepts of chemical kinetics are applied in many disciplines, such as chemical engineering, enzymology and environmental engineering.Objective

In this lab we are observing the behavior of the solution in different condition by temperature of the solution by one side or by proportion of the size of the solute. By this we want toachieve the knowledge of which fact affect the rate of a reaction in order to make it faster or even slower.
The main point of these experiment is to make easier the identification of the physicalproperties that affect a solution


EQUIPMENT REAGENTS:
1 50 mL beaker
1 paper towel
3 Alka—SeItzer Tablets (or other generic effervescent product)
Room temperature water
Warm water
Icewater
1 dropper
Hot plate
Beaker of WARM water
Timing Device

Procedure
1. Score an X on the back and break each of your tablets into FOUR pieces for the 8 (minimum)
trials youwill be conducting. (You have been given enough to do 12 trials ~ record ALL results)
2. Add approximately 20 mL of room temperature water into your tilm canister (about 2/3 full) and
drop one—fourthtablet into the water inside the canister, quickly cap and begin timing the reaction.
Upon completion of the reaction, record the time in seconds. Dispose ofthe used solution in the
canister into...
