Question

The conversion of vinyl allyl ether to pent-4-enol follows first-order kinetics. The following plot is obtained for such a reaction. Determine rate constant for the reaction.

• A. $4.6\times {10}^{-2}{s}^{-1}$
• B. $1.2\times {10}^{-2}{s}^{-1}$
• C. $2.3\times {10}^{-2}{s}^{-1}$
• D. $8.4\times {10}^{-2}{s}^{-1}$

Answer 1

The correct option is C $2.3\times {10}^{-2}{s}^{-1}$

$Slope=\frac{k}{-2.303}$
$⟹k=Slope\times (-2.303)$
$⟹k=\frac{-6}{10\times 60}\times (-2.3)$
$⟹k=2.3\times {10}^{-2}{s}^{-1}$
