Chemistry - Chemical Kinetics Question with Solution | TestHub

$\ell n\left(\frac{K_2}{K_1}\right)=\ell n\left(\frac{A_2}{A_1}\right)+\frac{\left(E_{a_2}-E_{a_1}\right)}{RT}$

$=\ln \left({\mathrm{e}}^{-2}\right)+\frac{(9-12)\times 10^3}{2\times 300}$

$=-2-5=-7$

$\Rightarrow {\mathrm{K}}_2<{\mathrm{K}}_1$

so z will be major product.

similarly solve for 800 K and result comes that Y will be major product so none of statement $\mathrm{A},\mathrm{B}$ and C is correct.
