Matter is anything that has mass and occupies space, It can exist in 3 states, or phases: solid, liquid, and gas.

Solid molecules are closely packed together and retain a fixed shape.

Liquid molecules aren't packed very closely, and take the shape of the bottom of the container.

Gas molecules are far apart and fill the container

completely.

Entalpy of vaporization of water is 41.1k/mol. if the vapor pressure of water at 373k is 101.3 kpa, what is the vapor pressure o
allsm [11]

Answer: The vapor pressure of water at 298 K is 3.565kPa.

Explanation:

The vapor pressure is determined by Clausius Clapeyron equation:

ln(\frac{P_2}{P_1})=\frac{\Delta H_{vap}}{R}(\frac{1}{T_1}-\frac{1}{T_2})

where,

P_1 = initial pressure at 298 K = ?

P_2 = final pressure at 373 K = 101.3 kPa

\Delta H_{vap} = enthalpy of vaporisation = 41.1 kJ/mol = 41100 J/mol

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 298 K

T_2 = final temperature = 373 K

Now put all the given values in this formula, we get

\log (\frac{101.3}{P_1})=\frac{41100}{2.303\times 8.314J/mole.K}[\frac{1}{298K}-\frac{1}{373K}]

\frac{101.3}{P_1}=antilog(1.448)

P_1=3.565kPa

Therefore, the vapor pressure of water at 298 K is 3.565kPa.
