(a) Use a graphing calculator or standard graphing software to make an Arrhenius plot of the data shown here for the decomposition of iodoethane into ethene and hydrogen iodide, C₂H₅I(g) → C₂H₄ (g) + HI(g), and determine the activation energy for the reaction.

(b) What is the value of the rate constant at 400°C?
