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.
the increase of pressure→
the decrease of moleculars motion distance→ the increae of condensation
c. K increase, decrease, or stay the same when mole fraction in the liquid phase is increase?
