A mixture containing $84\mathrm{.}2$ wt$\%$ SiCl$4$ and $15\mathrm{.}8$ wt$\%$ Zn is fed continuously

at a rate of $303$ g$/$h into a small laboratory$-$scale reactor. The reactor

operates at steady state. Inside the reactor, Si is produced by the following

reaction: SiCl$4+2$Zn $->$ Si $+2$ZnCl$2$

The reactor exit stream contains Si$,$ ZnCl$2,$ and SiCl$4.$ Calculate the flow

rate and composition of the exit stream. $($This reaction formed the basis for

the earliest commercial production of electronics$-$grade silicon, but has

been replaced by the Siemens process.$)$
