Dibromoethane and potassium iodide react in methanol (the solvent) according to the equation: \mathrm{C}_{2} \mathrm{H}_{4} \mathrm{Br}_{2}+3 \mathrm{KI} \rightarrow \mathrm{C}_{2} \mathrm{H}_{4}+2 \mathrm{KBr}+\mathrm{KI}_{3} The initial rate of this reaction was determined in

a series of experiments at 65 °C, giving the data below: \text { Experiment }\left[\mathrm{C}_{2} \mathrm{H}_{4} \mathrm{Br}_{2}\right] / \mathrm{mol} \mathrm{L}^{-1}[\mathrm{KI}] / \mathrm{mol} \mathrm{L}^{-1}+\left(\mathrm{d}\left[\mathrm{K} \mathrm{I}_{3}\right] / \mathrm{dt}\right) / \mathrm{mol} \mathrm{L}^{-1} \mathrm{~s}^{-1} 1 0.442 1.722 0.00574 0.4422.5830.008612. 3 1.109 1.722 0.0144. a) Determine the order of the reaction with respect to C2H4Br2 b) Determine the order of the reaction with respect to KI *0 *1 *2 *3 c) Determine the value of the rate constant and select the appropriate units for it. \begin{array}{l} \mathrm{Os}^{-1} \\ \mathrm{O} \mathrm{L} \mathrm{mol}^{-1} \mathrm{~s}^{-1} \\ \mathrm{O} \mathrm{L}^{2} \mathrm{~mol}^{-2} \mathrm{~s}^{-1} \end{array} NOTE: You can enter your answer either as a decimal or in scientific notation.To enter your answer in scientific notation, write the powers of 10 after the letter 'e'.For example: enter 1.24 x 10³ as 1.24e-3 or simply as 0.00124
