What is the pressure of 2 mole of O2O_{2} at H2H_{2} when its volume is 5 litre in vander Waal’s equation (a = 4.17, b = 0.03711).

A

10.33 atm

B

9.33 atm

C

9.74 atm

D

9.2 atm

Answer

9.33 atm

Explanation

Solution

PcP_{c}

PcP_{c}

P=2×.0821×3005−2×.03711−4.7×2252⇒10−0.66P = \frac { 2 \times .0821 \times 300 } { 5 - 2 \times .03711 } - \frac { 4.7 \times 2 ^ { 2 } } { 5 ^ { 2 } } \Rightarrow 10 - 0.66 O2,N2,NH3O_{2},N_{2},NH_{3}
