Unformatted text preview: 6. Data was obtained. 7. A 10 ml solution of benzophenone in isopropanol was created with enough solid solute to provide an absorbance of about 1/cm at 350 nm. 8. A few small fragments of a NaOH pellet were dissolved to make the solution alkaline. 9. N 2 was bubbled through the solution for saturation and removal of air. Data The data recorded would be similar to the data from Lab Report #1. The data would have more graphs because the solution will be excited at different intensities. Discussion The conjugate base of benzophenone absorbs at 600nm. Flash excitation was performed at different intensities. The initial concentration of the triplet state and the initial free radical concentration can be varied. The half-life for the second order reaction is dependent on the flash intensity. The extracted rate parameter from the fitting procedure is not....
