ln(21/39) = /8.314 [(1/345.15) - (1/294.35) = 1510 J/mol Results and Discussion Each trial had a different reaction rate and a different order of reaction. Temperature had an interesting effect on the rate of reaction. When we performed the experiment in a hot

water bath, the rate of reaction was much higher than it had been for any of the previous three trials. This is because an increase in temperature causes an increase more and more molecules to collide. The temperature will increase the molecular velocities which results in the collision of more molecules with a higher level of energy which will increase the reaction rate. Also, an increase in the concentration of reactants leads to more collisions which leads to a higher rate. The iodide ion was a catalyst in the experiment. It lowered the activation energy that was needed to start the chemical reaction causing an increase in the reaction rate. There are many possible errors that could have occurred in this experiment. The most obvious source of error is not having the lid of the wash bottle screwed on tight enough. This could result in air escaping and ultimately less product being collected in the graduated cylinder. We can conclude from this experiment that the higher the temperature, the higher the reaction rate. We can also

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
