Question
Periodic Chemical Reaction. Go on YouTube and search under the phase “reaction oscillante” (check to see if it looks like the screen shot below). Video link: https://www.youtube.com/watch?v=Ch93AKJm9os .Start the video and once the reaction gets under way find the time (in seconds) it takes the reaction to go from blue color to blue color(the color goes from blue, to clearish, to yellow, then back to blue). What this will give you is the period of this reaction, so if this reaction were modeled with a sine function like y = a sin(bx + c) that would be the number used to solve for “b”.
a) Period of the reaction is _______(secs)?
b) What is the name(it is based on the name of two people) given to these kinds of reactions?
réaction oscillante (à base d'iode) by educationsnet 3 years ago 3,727 views www.lachimie.net 1:14Explanation / Answer
1. In the video, the reaction is changing colours from blue color to blue color(the color goes from blue, to clear, to yellow, then back to blue). So, This whole blue to blue colour reaction is taking 10 s. After 10 s, the reaction starts another oscillation, i.e. the cycle of changing color starts again. One oscillation of reaction takes 10 s.
2. The reaction is commonly called as Briggs-Rauscher reaction. The name is on the two scientists. Otherwise these are also called as oscillation reactions.
