Chemistry 101: Temperature and Reaction Rate Lab Report

Sciences! The various disciplines, although studied separately, are connected and sometimes conflicting in a sense. And when it comes to determining how a rise and fall in temperature influences a reaction, different disciplines conflict.

First, there's kinetic energy, which is mostly about Physics, and the reaction of molecules, which is, of course, Chemistry. Get the connection? However, to determine the effect of temperature on the reaction rate, the researcher must complete an experiment and create a lab report on their findings. This way, they will have substantial results to prove the theory.

A Prelude to the Lab Report

Indeed, experimentation precedes a report. The aim of the experiment ought to be precise before coming up with a lab report. In this case, it is gauging the effect of temperature on the rate of reaction. You ought to have your apparatus and samples ready for the test. For instance, you might utilize sodium thiosulphate solution and Hydrochloric acid and play around with the temperature to see its effect.

Before beginning the experiment, you need to conduct some preliminary work to help you choose the appropriate tools for the job. Additionally, it will allow you to make sure that all your apparatus is cleaned sufficiently before beginning the experiment. Utilize the following steps to complete your test.

  • Add the right amount of sodium thiosulphate (10 cm3) and water (40cm3) into a conical flask. Put 5cm3 of HCL in a measuring cylinder.
  • Start warming the thiosulphate solution up to the desired temperature. The plan is to do this at least five times for specific temperature ranges.
  • Place the conical flask over a piece of paper with a cross drawn on it.
  • Put the acid and start the timer. Swirl the flask to ascertain everything mixes thoroughly and place it on a white paper. Record the temperature.
  • Check out the cross from above and when it disappears, stop the timer and note the time. Now, write down the final temperature in the flask.
  • When done, pour the solution down the drain.

You ought to be very careful when experimenting by protecting your eyes and hands. Also, note the figures carefully as they will be utilized in the lab report. If you do anything erroneously, you risk recording the wrong results that will, of course give you a poor interpretation. That is why keeping everything organized in your experiment table will help you yield ideal results.

What Happens and What Do the Findings Mean?

Scientific theory states that at higher temperatures, because of an increase in kinetic energy of reactant molecules, reactions proceed faster. Do the experiment and subsequent lab report agree with the theory?

Of course, an increase in temperature makes it more likely for molecules to collide as they have sufficient energy. And you will notice that from your lab results, whenever you increased the temperature, the reaction increased. Such are the marvels of Chemistry and Physics, and you can find about whatever you desire from a lab experiment.
