LAB DESCRIPTION This laboratory investigates the eftect of temperature on a chemc al reaction rom lil reacting aith in i to produce on and tin IV You might wite this reaction as follows Fe is the chemical symbot for iron Sn is the chemic al symbot for tin Both symbois come trom ther Latin names temum tor ron and stannum for tin Unlike many chemic al reactions, this one proceeds slowty enough to record its progress over the span of a few minutes. As the clear tin ions react with the iron the resulting ions Fe"2 and Sn" are colorless You see the red solution losing its color The concentrations of the chemicals are important in chemc at reactions This experiment uses a color bar to record data You must click on the color in the bar that most closely resembles that of the solution at each frame of the video 1 Ice melting to water is an example of a physical reaction Which of the following temperatures do you believe will cause this reaction to proceed the fastest? O Ice in the frdge at 5"C O Ice at room temperature. 20"C O Ice in the oven at 200 C O Ice in the freezer at O'C 2 Two clear liquids are mixed and the result is a clear solution Do you think this means that no reaction could have occurred O Yes O No 3 Reaction rate can be affected by many things In your opinion, which of the following could not affect the speed of a reaction? O Temperature O Concentration of reactants Color of reactants

Explanation / Answer

2 yes

3 colur of reactant.
