Answer:

The least reactive atoms are those with a filled set of orbitals (octet). The stability of the electrons in atoms determines not only the reactivity of an atom but its valence and the type of chemical bonds it can form.

Hope this helps -_- :)

Answer : The temperature of liquid is, 369.9 K

Explanation :

The Clausius- Clapeyron equation is :

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

where,

$P_1$ = vapor pressure of liquid at 373 K = 681 torr

$P_2$ = vapor pressure of liquid at normal boiling point = 760 torr

$T_1$ = temperature of liquid = ?

$T_2$ = normal boiling point of liquid = 373 K

$\Delta H_{vap}$ = heat of vaporization = 40.7 kJ/mole = 40700 J/mole

R = universal constant = 8.314 J/K.mole

Now put all the given values in the above formula, we get:

$\ln (\frac{760torr}{681torr})=\frac{40700J/mole}{8.314J/K.mole}\times (\frac{1}{T_1}-\frac{1}{373K})$

$T_1=369.907K\approx 369.9K$

Hence, the temperature of liquid is, 369.9 K
