The hydrolysis of an organic compound is known to be mainly base-catalyzed with a rate constant of \( \mathrm{kb} \) : 0.98 1/M.s. Calculate the half-life of this compound assuming pseudo-first order kinetics for its degradation at a \( \mathrm{pH} \) of 10 and a starting concentration of \( 10^{-3} \mathrm{M} \). How will the half-life change if the reaction has zero-order kinetics? Compare the corresponding half-lifes assuming the same rate of hydrolysis in zero-order with the unit of \( \mathrm{M} / \mathrm{s} \). How will the result change if the starting concentration is \( 10^{-1} \mathrm{M} \) for both cases?
