This lab focused on three factors affecting reaction rates‚ temperature‚ surface area‚ and concentration. Our first experiment (table 1) looked mainly into the effects of temperature on the reaction rate. To see how different temperatures would change the reaction rates we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams
