Question

In each of the following processes indicate whether the fugacity of component 1 goes up, stays the same, or goes down. Give a brief reason (1 pt. Each) (a) Pure ideal gaseous 1 is heated isobarically (b) Pure ideal gaseous 1 is compressed isothermally (c)Pure liquid 1 is heated (d) An ideal liquid mixture of 1 and 2 is compressed isothermally (e)Liquid 1 is mixed with liquid 2, which forms an ideal mixture (f) Apure liquid at its boiling temperature is isothermally converted into vapor (g)Pure liquid 2 is added to liquid 1; and 1 and 2 are completely immiscible (h) 1 is a component of an ideal gas mixture that is compressed isothermally (i)1 is originally in a liquid mixture with 2, but is instead mixed with 3 that has similar properties but has a much larger molecular structure )1 is originally in a liquid mixture with 2, in equilibrium with an ideal gaseous mixture. A (k) An ideal liquid mixture of 1 and 2 is heated (4 pts.) Is fugacity a state variable? Why? large quantity of a third ideal gas, insoluble in the liquid, is added to the vapor phase

Explanation / Answer

1) Fugacity increases the same way as pressure increase with increase in T at constant volume
a) Pure ideal gaseous 1 is heated isobarically(constant pressure) - as the pressure is constant fugacity will not go up as the corresponding volume increases.
b) Pure ideal gaseous 1 is compressed isothermally: As the temperature remains constant, volume decreases and pressure increases and concentration of gasesous molecules increases with increase in pressure - Fugacity goes up
c) Pure liquid is heated - Fugacity increases with increase in temperature - yes it goes up
d) An ideal mixture compressed isothermally - Increase the pressure and the concentration of the mixture and interactions - Fugacity goes up.
