Use the data from experimental trials 1 and 2. When the concentration of C2H5OH doubles from 0.15M to 0.30M, what happens to the initial rate? What kinetic order is present? Use experiments 2 and 3. When the concentration of Cr2O72- doubles from 0.050 M to 0.10 M, what happens to the initial rate? What kinetic order is presentWhen the concentration of H+ increases from 0.010M to 0.100 M, what happens to the initial rate? What kinetic order is present? Use experimental trials 2 and 4. Using the data from experiment 1, solve the reaction rate constant, K. Calculate the overall reaction order.
