A certain reactant ${\mathrm{B}}^{\mathrm{n}+}$ is getting converted to ${\mathrm{B}}^{(\mathrm{n}+4)+}$ in solution. The rate constant of this reaction is measured by titrating a volume of the solution with a reducing reagent which only reacts with ${\mathrm{B}}^{\mathrm{n}+}$ and ${\mathrm{B}}^{(\mathrm{n}+4)+}$. In this process, it converts ${\mathrm{B}}^{\mathrm{n}+}$ to ${\mathrm{B}}^{(\mathrm{n}-2)+}$ and $B^{(n+4)+}$ to $B^{(n-1)+}$. At $t=0$, the volume of the reagent consumed is 25 ml and $t\mathrm{t}=$ 10 min , the volume used up is 32 ml . Calculate the rate constant of the conversion of ${\mathrm{B}}^{\mathrm{n}+}$ to ${\mathrm{B}}^{(\mathrm{n}+4)+}($ in min ${}^{-1})$ assuming it to be a first order reaction.
