8. How will doubling the concentration of H20 in the following reaction impact the rate? CI +H20 A. Double the rate B. Halve the rate C. Quadruple the rate D. No change to the rate Solution H2O Concentration will not impact the rate because this reaction occurs in two step . First step is broken of Cl bond and second step is attack of H2O molecule.Firs t step is rate determining step. So concentration of H2O will not impact. First step is slow step. option D is correct If satisfied please rate it. Thanks Any query please comment. .
