Here is the continuation of the procedure:

Procedure:

Label three 250 $\text{cm}^3$ beakers as A, B, and C.
Pour 100 $\text{cm}^3$ of distilled water into each beaker using a measuring cylinder.
Step 3
- For beaker A, leave the water at room temperature. Measure and record its temperature using a thermometer.
- For beaker B, gently heat the water to approximately 50 °C using the heating plate/Bunsen burner with a tripod stand and gauze. Use a thermometer to monitor and maintain this temperature.
- For beaker C, place the beaker in an ice bath to cool the water to approximately 5 °C. Use a thermometer to monitor and maintain this temperature.
Using a dropper/pipette, carefully add 1 $\text{cm}^3$ of potassium manganate(VII) solution (BA1) to the bottom center of the water in beaker A, ensuring minimal disturbance.
Immediately start the stopwatch.
Measure the time taken for the purple colour to spread a predetermined distance (e.g., 5 cm radius from the initial drop) or to reach a specific height in the beaker. Use a ruler to measure the distance.
Record the initial temperature of the water and the time taken for diffusion in a table.
Repeat Steps 4-6 for beaker B (heated water) and beaker C (cooled water).
Repeat the entire experiment (Steps 2-7) at least two more times for each temperature to ensure the reliability of the results.
Calculate the average time taken for diffusion at each temperature.
Plot a graph of temperature (independent variable) against the rate of diffusion (dependent variable, which can be represented as 1/time or distance/time).
