Question
The equilibrium N2 (g) + O2 (g) ⇋ 2NO (g) is estabilished in a reaction vessel of 2.5 L capacity. The amounts of N2 and O2 taken at the start were respectively 2 moles and 4 moles. Half a mole of nitrogen has been used up at equilibrium. The molar concentration of nitric oxide is :
Options
A.0.2
B.0.4
C.0.6
D.0.1
Solution
N2 + O2 ⇋ 2NO
Initial 2 moles 4moles
At Eq. 2 -
4 - 
2 × 
= 1 mol
Molar concentration of NO at equilibrium =
= 0.4
Initial 2 moles 4moles
At Eq. 2 -
4 - 2 × = 1 molMolar concentration of NO at equilibrium =
= 0.4Create a free account to view solution
