Question: how does temperature affect the rate of a reaction? hypothesis: the higher the temperature, the faster the particles. the lower, the slower. materials two cups or jars antacid tablets thermometer (if you have one) timing device procedure fill cup one with room temperature water, cup 2 with hot water, and cup 3 with ice water. you can take the temperature of the water if you have a thermometer. add one tablet to each cup and record how long it took for the antacid tablet to dissolve. repeat experiment two more times. try to use the same temperature water each time. data room temp water! water temperature (*f) (should be the same each time! ) time (s) trial 1 trial 2 trial 3 average hot water water temperature (*f) (should be the same each time! ) time (s) trial 1 trial 2 trial 3 average ice water water temperature (*f) (should be the same each time! ) time (s) trial 1 trial 2 trial 3 average conclusion – be sure you answer the original question and describe whether or not your hypothesis was correct.
