For a first order reaction, $\mathrm{A}\left(\mathrm{g}\right)\to \mathrm{B}\left(\mathrm{g}\right)$ at $35°\mathrm{C},$ the volume of $\mathrm{A}$ left in reaction vessel at various times are given below. $[$ Given data $:\log (5/4)=0.096.$

What is the value of rate constant ?

Find the unit of the rate constant of a reaction represented with a rate equation, rate $=k{\left[A\right]}^{\frac{1}{2}} {\left[B\right]}^{\frac{3}{2}}$

The rate constant of a first order reaction is $231\times {10}^{-5} {\mathrm{s}}^{-1}$. How long will $4 \mathrm{g}$ of this reactant reduce to $2 \mathrm{g}$?

The data given below are for the reaction of $A$ and $D_2$ to form product at $295K$ . Find the correct rate expression for this reaction
 

Under what condition the order of the reaction,

$2HI\to H_2\left(g\right)+I_2\left(g\right),$ is zero

An endothermic reaction $\mathrm{A}\to \mathrm{B}$ has an activation energy of $13\mathrm{kJ} {\mathrm{mol}}^{-1}$ and the enthalpy change for the reaction is $2\mathrm{kJ} {\mathrm{mol}}^{-1}$. The activation energy of the reaction $\mathrm{B}\to \mathrm{A}$ is
