Acertain liquid has a vapor pressure of 92.0 torr at 23.0 °c and 351.0 torr at 45.0 °c. calculate the value of δh°vap for this liquid.

Answer : The value of is 47.627 kJ/mol

Explanation :

To calculate of the reaction, we use clausius claypron equation, which is:

where,

= vapor pressure at temperature = 92 torr

= vapor pressure at temperature = 351 torr

= Enthalpy of vaporization = ?

R = Gas constant = 8.314 J/mol K

= initial temperature =

= final temperature =

Putting values in above equation, we get:

Therefore, the value of is 47.627 kJ/mol

if you're asking what comes out, it's steam.
