본문내용

A8. For a typical straight-chain hydrocarbon, does:

K=y/x

x=mole fraction of methanol in Liquid

y=mole fraction of methanol in gas

a. K increase, decrease, or stay the same when temperature is increased?

If the problem should be assumed the constant pressure(∆P=0),the K value^' ll increase when the temperature is increased.

the increase of tempature→ increase of internal energy

→ the increase of molecular motion rate → the increase of vaporization

b. K increase, decrease, or stay the same when pressure is increased?

If the problem should be assumed the constant temperature(∆T=0),the K value^' ll decrease when the pressure is increased.
