For my rate of reaction experiment I have to answer the question "why did we ask you to measure the room termperature and temperature of reaction solutions".
For the experiment we used 5 flasks and we put one of them in an ice bath at 6-10 degrees C.
My answer is that we recorded the temps so that we could see how changing the temperature would affect the rate of reaction.
Does my answer make sense?
Also, the flask that was placed in the ice bath was suppose to have the longest reaction time but I am not sure why? Would this be because the cold caused the thiosulfate ions to be consumed more slowly??
That's true but you should include how the temperature affected the rate and which way the equilibrium shifted and how the color change tells you which way it shifted.
When you heat the test tube the solution turned a dark purple/blue color. And when you take the test give out of the boiling hot water it begins to cool and turns back to its original color pink. And when you put the test tube in a ice bath, the test tube turned pink, and when you took it out of the ice bath it turned back to its original color. You need to then include whether it is exothermic or exothermic.
The ice bath one would take longer because it takes more energy for the solution in the flask to form products thus, the activation energy is higher making the reactants need energy so it is endothermic.
Yes, your answer makes sense. Measuring the room temperature and the temperature of the reaction solutions is important in a rate of reaction experiment because temperature can significantly affect the rate at which a reaction occurs.
By recording the temperatures, you can analyze how changes in temperature impact the rate of reaction. This allows you to observe if the reaction rate increases or decreases with temperature variations, and it helps in understanding the relationship between temperature and reaction rate.
Regarding the flask placed in the ice bath, you are correct that the cold temperature would generally slow down the reaction. In this specific context, the thiosulfate ions might be consumed more slowly due to the decrease in temperature. This can happen because lower temperatures can reduce the kinetic energy of the reacting particles, making successful collisions less frequent and decreasing the reaction rate.
In summary, measuring temperatures allows you to investigate the effect of temperature on the rate of reaction and analyze how different temperature conditions impact reaction rates.
