What will be the CORRECT unit of rate constant $\mathrm{k}$ for a reaction whose order is three ?

The rate of a reaction is found to depend upon two concentration variables. What should be the order of the reaction?

What will be the order of the reaction for hydrolysis of methyl acetate with $\mathrm{NaOH}$ by using the data provided?

Time $\left(\min \right) 0 5 10 15$
Volume of acid $\left(\mathrm{mL}\right) 10.12 6.24 1.40 0.981$

The following equation is the Arrhenius Equation. $\mathrm{k}={\mathrm{Ae}}^{-\mathrm{Ea}/\mathrm{RT}},$ where ${\mathrm{E}}_{\mathrm{a}}$ is the minimum energy molecules must possess in order to react to form a product, $\mathrm{k}$ is the rate constant, $\mathrm{A}$ is the frequency factor, $\mathrm{R}$ is the gas constant and $\mathrm{T}$ is the Kelvin temperature. Under normal circumstances, the Arrhenius plot is obtained by plotting

What will be the value of activation energy $\left({\mathrm{E}}_{\mathrm{a}}\right.$ in $\mathrm{kJ}$ ) and rate constant ( $\mathrm{k}$ in ${\min }^{-1}$ ) for the given equation at $27{}^{\circ }\mathrm{C}?$ The equation$\mathrm{lnk}=-2576/\mathrm{T}+12.1$
