Ea R Rate [time value of k Using the exponents x,y, and z determined in Part 1, determine the value of k at the temperature of the water bath. What effect did the increase in temperature have on the value of k? Using the Arrehius equation, determine the Ea in kJ/mol for the iodination of acetone. R= 8.314 J/(mol x K) In k_ (t. t.) k
