Question

The normal boiling point of toluene is 110.6°c. What is its vapor pressure at this temperature

Answer 1

Answer:

Explanation:

Here we can use Clausius-Clapeyron-equation to find the vapour pressure .

But as the here temperature in this cases same as the normal temperature is the vapour pressure at the state will be zero

Since vapour pressure

P=px(Hv/R(((1/t1)-(1/t2)))

Here p=1atm

Hv=enthalpy of vapourisation =39200J

As here t1=t2=110.6 hence the vapour pressure will be zero
