Question

compute reaction rates for all seven trials
assume that each tablets mass was 1,000 mg, and remember that you used 0.200 l of water each time. compute the reaction rate to the nearest whole number using the formula below.
reaction rate = \\(\frac{\text{mass of tablet} \\ / \\ \text{volume of water}}{\text{reaction time}}\\)
3°c reaction time = 138.5 sec
reaction rate = 36 mg/l/sec
24°c reaction time = 34.2 sec
reaction rate = 146 mg/l/sec
40°c reaction time = 26.3 sec
reaction rate = 190 mg/l/sec
65°c reaction time = 14.2 sec
reaction rate = 352 mg/l/sec
full tablet reaction time = 34.5 sec
reaction rate = \\(\square\\) mg/l/sec
eight pieces reaction time = 28.9 sec
reaction rate = \\(\square\\) mg/l/sec
tiny pieces reaction time = 23.1 sec
reaction rate = \\(\square\\) mg/l/sec

Explanation:

Step1: Define given values

Mass of tablet = 1000 mg, Volume of water = 0.200 L

Step2: Calculate full tablet rate

Substitute into formula: $\text{Reaction Rate} = \frac{1000 / 0.200}{34.5} = \frac{5000}{34.5} \approx 29$

Step3: Calculate eight pieces rate

Substitute into formula: $\text{Reaction Rate} = \frac{1000 / 0.200}{28.9} = \frac{5000}{28.9} \approx 35$

Step4: Calculate tiny pieces rate

Substitute into formula: $\text{Reaction Rate} = \frac{1000 / 0.200}{23.1} = \frac{5000}{23.1} \approx 43$

Answer:

Full tablet: 29 mg/L/sec
Eight pieces: 35 mg/L/sec
Tiny pieces: 43 mg/L/sec
