ln(k) = -E_a/R 1/T + ln(A) A plot of ln (k)versus 1/T result in a straight line with a slope = -E_a/R. The value of E_a can then be calculated using the value of R and to the slope of the line. This experiment uses the Arrhenius equation, which relates the temperature and specific reaction rate constant to determine the activation energy for the crystal violet reaction. The reaction will be performed at different temperatures. Once the order of reaction...
