Question
Calculate the pressure of one mole of nitrogen gas in a 10 L cylinder at 50∘C using the Van der Waal's equation.Also find the value of ideal gas pressure.(Van der Waal's constants a and b for nitrogen are 1.4L2 atm mol−2 and 0.04 L2mol−1 respectively) .
Answer: Option D
:
D
From Van der Waal's equation ,
⟮p+aV2⟯⟮V−b⟯=RT
We get ,
⟮p+1.4100(10−0.04)=0.0821×323⇒p=2.648atm
From ideal gas equation, we have
p=RTV=0.0821×32310=2.652
Pideal=2.648atmPreal=2.652atm
