Help please EXERCISE No $1($Based on Textbook, problem No $14\mathrm{.}1,$ page $575)-15$ points: A stream containing $3$ moles

of $H_2{S}_{(g)}$ for every $5$ moles of $O_2(g)$ enters a chemical reactor. The $H_2{S}_{(g)}$ is oxidized to $S{O}_{2(g)}$ according to

the stoichiometry below. Develop expressions for the mole fractions of species exiting the reactor as

functions of the equilibrium reaction coordinate, ${}_{eq}.$

$2H_2{S}_{(g)}+3O_{2(g)}$harr$2H_2{O}_{(g)}+2S{O}_{2(g)}$
