+ R Part 2 Effect of Temperature on the Reaction Rate: Determination of the Activation Energy The dependence of the rate constant with temperature is given by the equation below. -E In(k) - (2) 7) + Inca) where k is the rate constant, E, is the activation energy, R is the Ideal Gas Constant in terms of energy, A is the Arrhenius constant, and T is the temperature in Kelvin Since the equation deals with exponentials, do not round results too much, keep at least 4 significant figures. Determine the rate of reaction using Equation 1. Using the calculated rate and the orders rounded to whole numbers found in Part I with the concentrations for Reaction Mixture 1, determine the rate constant. Plot the In(k) versus 1/T using a spreadsheet or by hand on graph. In Excel, add a trendline and show the linear regression and R squared. Print the graph with appropriate labels for the axes and title (10 points). Using the results from the plot, calculate the activation energy and the Arrhenius or Frequency factor (10 points).
