The OH- radical disproportionates according to the elementary chemical reaction OH +OF →E0+0
This reaction is second-order in OH. The rate constant for the reaction is 2.0 x 10-42 cm molecules at room
temperature. If the initial OH- concentration is 14 x 10" molecules/cm, what is the first half-life for the reaction?
O 7.1 * 10"
O 3.6* 10-25
O 18 10-25
O 28 x 1015
O 3.5% 1011
