For the reaction R-X+OH ROH+X- The rate is given of

Rate=5.0×10-5R-XOH-+0.20×10-5R-X what percentage of R-X Reaction by SN2 mechanism when OH-=1.0×10-2M

(A) 96.1%                                                         

(B) 3.9%

(C) 80%                                                           

(D) 20%

(D) RateSN2=5.0×105×10-2R-X=5.0×10-7R×XRate SN1=0.20×10-5R-X%of SN2=5×10-7R-X×1005×10-7R-X+0.20×10-5R-X=20
