The normal boiling point of bromine is 58.8°C, and its enthalpy of vaporization is 30.91 kJ/mol. What is the approximate vapor pressure of bromine at 10.0°C?

Answer : The vapor pressure of bromine at is 0.1448 atm.

Explanation :

The Clausius- Clapeyron equation is :

where,

= vapor pressure of bromine at = ?

= vapor pressure of propane at normal boiling point = 1 atm

= temperature of propane =

= normal boiling point of bromine =

= heat of vaporization = 30.91 kJ/mole = 30910 J/mole

R = universal constant = 8.314 J/K.mole

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

Hence, the vapor pressure of bromine at is 0.1448 atm.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
