answer boxed question

Y +] y [X(+)]= ax(t) is an equation that describes vapor-liquid 1 + (0-1) XC6) equilibria (Y-values) in a binary system. a( X d = relance volatility assume this is a known constant) X(+) = time dependent mole fraction of a component in the liquid prase Y(+) = in the vapor phase -assume X(O)=Xs and Yo-Ys are known constants Manucily derive me Taylor series approximaron for y[xc+]
