The reaction between ethyl iodide and hydroxide ion in ethanol (c2h5oh) solution, c2h5oh + oh --> c2h5oh + I, has an activation energy of 86.8 kj/mol and a frequency factor of 2.1 x 10^ 11 and a rate constant, k, of 2.81 x 10^ -4 at 32 degrees Celcius. A solution of KOH in ethanol is made up by dissolving 0.341 g KOH in ethanol to form 289.0 ml of solution. Similarly, 1.523 g of C2H5I is dissolved in ethanol to form 289.0 of solution. Equal volumes of the two solutions are mixed. Assuming the reaction is first order in each reactant, what is the initial rate at 32 degrees C?
