Calculate the mass flux of reactant A to a single catalyst pellet $1$ cm in diameter suspended in a large body of liquid. The reactant is present in dilute concentration and the reaction is considered to take place instantaneously at the external surface $($ie$.,$ CAs ~ $0).$ The bulk concentration of the reactant is $1\mathrm{.}0$M$,$ and the free$-$system liquid velocity is $0\mathrm{.}1$ m$/$s$.$ The kinematic viscosity is $0\mathrm{.}5$ centistoke $(1$cs $=10-6$ m$2/$s$,$ and the liquid diffusivity of A is $10-10$ m$2/$s$.$ T $=300$K$.$
