Question

Assume that each tablet's mass was 1,000 mg, and remember that you used 0,200 L of water each time,

Answer 1

For every temperature you use the formula given by the question.

at 3°C you have:

Reaction rate = (1000/0.2)/138.5 = 36 mg/L/sec

at 24°C you have:

Reaction rate = (1000/0.2)/34.2 = 146 mg/L/sec

at 40°C you have:

Reaction rate = (1000/0.2)/26.3 = 190 mg/L/sec

at 65°C you have:

Reaction rate = (1000/0.2)/14.2 = 352 mg/L/sec

Answer 2

Answer :

The reaction rate at $3^oC$ is, 36.1 mg/L/sec

The reaction rate at $24^oC$ is, 146.2 mg/L/sec

The reaction rate at $40^oC$ is, 190.1 mg/L/sec

The reaction rate at $65^oC$ is, 352.1 mg/L/sec

Explanation :

Formula used :

$\text{Reaction time}=\frac{(\text{Mass of tablet })/(\text{ volume of water})}{\text{Reaction time}}$

For $3^oC$ :

$\text{Reaction time}=\frac{(1000mg)/(0.200L)}{138.5sec}=36.1mg/L/sec$

For $24^oC$ :

$\text{Reaction time}=\frac{(1000mg)/(0.200L)}{34.2sec}=146.2mg/L/sec$

For $40^oC$ :

$\text{Reaction time}=\frac{(1000mg)/(0.200L)}{26.3sec}=190.1mg/L/sec$

For $65^oC$ :

$\text{Reaction time}=\frac{(1000mg)/(0.200L)}{14.2sec}=352.1mg/L/sec$
