Step 4: Measure the reaction rate at approximately 65 degrees Celsius.

Using tongs, place the 250 mL beaker on the hot plate.

Answer :

Final answer:

To measure the reaction rate at approximately 65 degrees Celsius, use tongs to place a 250mL beaker on a hot plate, monitor the reaction with a thermometer, and ensure safe handling by using boiling stones or a magnetic stir bar. Record all observations including temperature changes and reactions in the mixture for accurate analysis of the reaction rate.

Explanation:

Measuring the Reaction Rate at 65 Degrees Celsius

To measure the reaction rate at approximately 65 degrees Celsius, you need to follow the safety protocol and use tongs to place the 250mL beaker on the hot plate. It is crucial to carefully heat the reaction mixture and use appropriate tools such as a thermometer to monitor the temperature precisely. The reaction rate can be affected by temperature, and performing the experiment at the correct temperature ensures accurate results.

For reactions that require heating, adding boiling stones or a magnetic stir bar can prevent the solution from bumping. Secure the reaction vessel with a metal extension clamp and observe safety measures at all times. Refer to the experimental setup, like the one explained with the medium test tube and determine the temperature at which the sample reflux occurs, ensuring vapors are contained.

Once the desired temperature is reached and the reaction initiates, record any observations, including color changes or physical state alterations. After the reaction commences, it’s important to let the product cool before further handling. All of these steps must be documented for a comprehensive understanding of the chemical properties and reaction rates involved.
