Objectives/Goals Reaction rate is what determines when bombs go off, and how we digest food. But can you change the speed it occurs? In order to find this out, I took two possible factors, particle size and temperature, and put them to the test. This project will look at the effects of both particle size and temperature on reaction rate. Methods/Materials These factors will be tested with alka-seltzers inside a gas collecting apparatus (air tight bottle connected by tube into a graduated cylinder filled with water). For particle size, 3 trials were done for 4 different particle-sizes (Whole seltzer, Half, Quarters, Powder). Trials were done for particle size by dropping the tablet into the bottle and quickly shutting the cap. For testing temperature I did 3 trials for 3 different temperatures (Room Temperature, Cold, Boiling). Trials were done by pouring the water until the standardized level has been reached, and dropping a whole alka-seltzer into the bottle and quickly ...
