For the following reactions



where,


${\mathrm{k}}_{\mathrm{s}}$ and ${\mathrm{k}}_{\mathrm{e}}$ , are respectively, the rate constants for substitution and elimination, and $\mathrm{\mu }=\frac{{\mathrm{k}}_{\mathrm{s}}}{{\mathrm{k}}_{\mathrm{e}}}$ , the correct option is ________

Consider the following reactions
$\mathrm{A}\to \mathrm{P}1;\mathrm{B}\to \mathrm{P}2;\mathrm{C}\to \mathrm{P}3;\mathrm{D}\to \mathrm{P}4$
The order of the above reactions are $\mathrm{a}, \mathrm{b}, \mathrm{c} \mathrm{and} \mathrm{d},$respectively. The following graph is obtained when log[rate] vs.log[conc.] are plotted:

  
Among the following, the correct sequence for the order of the reactions is :

The rate constant $\left(k\right)$ of a reaction is measured at different temperature $\left(T\right)$, and the data are plotted in the given figure. the activation energy of the reaction in ${\mathrm{kJmol}}^{-1}$ is : $(\mathrm{R}$ is gas constant)
