Question

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 = (mass of tablet / volume of water) / reaction time. 3°c reaction time = 138.5 sec reaction rate = □ mg/l/sec 24°c reaction time = 34.2 sec reaction rate = □ mg/l/sec 40°c reaction time = 26.3 sec reaction rate = □ mg/l/sec 65°c reaction time = 14.2 sec reaction rate = □ mg/l/sec done

Explanation:

Step1: Identify given values

Mass of tablet = 1000 mg, Volume of water = 0.200 L, Reaction time for each case is given. Formula: \( \text{Reaction Rate} = \frac{\text{mass of tablet} / \text{volume of water}}{\text{reaction time}} \)

Step2: Calculate for \( 3^\circ\text{C} \)

First, \( \frac{\text{mass}}{\text{volume}} = \frac{1000}{0.200} = 5000 \) mg/L. Then, Reaction Rate = \( \frac{5000}{138.5} \approx 36 \) mg/L/sec.

Step3: Calculate for \( 24^\circ\text{C} \)

\( \frac{5000}{34.2} \approx 146 \) mg/L/sec.

Step4: Calculate for \( 40^\circ\text{C} \)

\( \frac{5000}{26.3} \approx 190 \) mg/L/sec.

Step5: Calculate for \( 65^\circ\text{C} \)

\( \frac{5000}{14.2} \approx 352 \) mg/L/sec.

Answer:

For \( 3^\circ\text{C} \): 36
For \( 24^\circ\text{C} \): 146
For \( 40^\circ\text{C} \): 190
For \( 65^\circ\text{C} \): 352
