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.

Activity two: just lemons, inc. production here's a one-batch sample of just lemons lemonade production. determine the percent yield and amount of leftover ingredients for lemonade production and place your answers in the data chart. hint: complete stoichiometry calculations for each ingredient to determine the theoretical yield. complete a limiting reactant-to-excess reactant calculation for both excess ingredients. water sugar lemon juice lemonade percent yield leftover ingredients 946.36 g 196.86 g 193.37 g 2050.25 g 89% just lemons lemonade recipe equation: 2 water + sugar + lemon juice = 4 lemonade mole conversion factors: 1 mole of water = 1 cup = 236.59 g 1 mole of sugar = 1 cup = 225 g 1 mole of lemon juice = 1 cup = 257.83 g 1 mole of lemonade = 1 cup = 719.42 g show your calculations below. analysis questions 1. based on taste observations only, which ingredients were in excess in the lemonade samples in activity one? in activity one the excess substances for each sample were the water and sugar. 2. based on the data in activity two, which excess ingredients are affecting the taste of the lemonade in the sample batch? 3. what can just lemons, inc. do during production to reduce the amount of excess ingredients and improve the taste of their lemonade? 4. try to reduce the amount of leftover ingredients by changing the amount of one, two, or all three starting ingredients. show your stoichiometric calculations below. 5. during factory inspection, just lemons, inc. discovered that a water valve to the lemonade mixing station was not functioning. once they repair it, more water will enter the mixing station. from what you know about the limiting and excess ingredients for current lemonade production, what advice would you give engineers about the upcoming increase in water?
