A mixture of two liquids X and Y, is boiling. At any time t there is present in the mixture a quantity x of one and y of the other. The ratio of the amounts of X and Y passing off at any one time is proportional to the ratio of the quantities still in the liquid state. Prove that [tex] y=Cx^k \\ [/tex], where C and k are constant.(adsbygoogle = window.adsbygoogle || []).push({});

I really don't know how to start this off, I have [tex] \frac{X}{Y} \propto \frac{x}{y} \\ [/tex]. What is the next step? Do I express X in terms of x and Y in terms of y? Thanks for helping.
