reaction produced. The reaction time was recorded. Steps above were repeated using cold 1.0 M HCI in an ice bath in a fume hood instead of room temperature 1.0 M HCI. Part C: The Effect of Concentration on the Rate of a Reaction 20 mL of 3.0 M HCI were measured into a 50 mL beaker. Exactly 1.00 gram of powdered CaCO 3 was obtained. CaCO 3 powder was placed into the 20 mL of 3.0 M HCI and the reaction time was recorded using a stopwatch. The timer was stopped when there was no more reaction produced. The reaction time was recorded. Part D: The Effect of Using a Catalyst on the Rate of a Reaction About 10 mL of 30% hydrogen peroxide (H 2 H 2 ) were poured into a small flask. About 5 mL of soap were poured into the small flask. 3 drops of food coloring were added into the small flask. About 3 mL of the catalyst, potassium iodide was measured in a small graduated cylinder. 3 mL of potassium iodide (KI) were added to the flask. The observation of the reaction was recorded in the data section below. Data: Mass of CaCO 3 used: 4g Reaction Temperature (of HCI) Reaction Time (seconds) Part A: Marble chips (chunks of CaCO 3 ) in room temperature 1.0 M HCI 23.7 0 C Over 600 seconds Part B, Reaction 1: Powdered CaCO 3 in room temperature 1.0 M HCI 22.4 0 C 21.98 seconds Part B, Reaction 2: Powdered CaCO 3 in cold 1.0 M HCI 7.6 0 C 1153.76 seconds
