Question

The following data were observed for the following reaction at `25^(@)C, CH_(3)OH + (C_(6)H_(5))_(3)C Clrarr(C_(6)H_(5))_(3)C.OCH_(3)+HCl`

Rates `(d[C])/(dt)` in sets I, II, and III are, respectively,
(in `M min^(-1)`):
A. `{:(I,II,III),(1.30xx10^(-4),2.6xx10^(-4),1.02xx10^(-3)):}`
B. `{:(I,II,III),(0.033,0.0039,0.0077):}`
C. `{:(I,II,III),(0.02xx10^(-4),0.04xx10^(-4),0.017):}`
D. None of above

Answer 1

Correct Answer - A
(I)Rate `=(dc)/(dt)=((Deltac)/(Deltat))=.0033/25=1.32xx10^(-4)`
(II)Rate `=(dc)/(dt)=((Deltac)/(Deltat))=.0039/15=2.6xx10^(-4)`
(III)Rate `=((Deltac)/(Deltat))=.0077/15=1.02xx10^(-3)`
