Essay On Temperature Of Bung

Powerful Essays
Background Information:

Carbon Dioxide is simply made by the reaction of sodium bicarbonate and vinegar.
When vinegar with high temperature meets the sodium bicarbonate, the molecules inside of the flask move actively around the space because they gain kinetic energy. When moving around the space, the molecules mix and react with each other faster making a big chemical reaction. Through this, the bung pops faster due to the actively moving molecules inside the hot temperature flask, which is similar to the movement of gas in the kinetic theory. On the other hand, when the vinegar with low temperature meets the sodium bicarbonate, the molecules do not mix well and react slowly to each other because the molecules are closer to each other like solids in the kinetic theory. By this, the bung pops up slower in the low temperature flask due to the not actively moving molecules. This idea is referred to as the Endothermic Process Na2CO3(s) + H2O (l) +CO2 (g)> where both the hot and cold temperature absorbs its heat making a chemical reaction. < CHEMISTRY TEXTBOOK pg. 538 – Endothermic Process>

How will the changes in temperature of the vinegar influence the time period for a chemical reaction?


If the temperature of the white vinegar (acetic acid) is higher, then the rate of reaction will occur faster when touching the sodium bicarbonate because due to the molecules moving actively in hot temperatures, the amount of carbon dioxide may form more quickly inside the flask leading the bung to pop faster.
