Question

during the formation of nitric oxide initially 15 moles of nitrogen and 5.6 moles of o2 is taken in 6 ltr container .at equillibrium state 10 moles of nitric oxide is formed .the equillibrium constatnt will be

Answer 1

N 2 +O2 ⇌2NO

• At t = 0            2          4         0

• At eq.            2-x    4-x       2x

Half a mole of nitrogen is used up at equilibrium,

x=0.5

So, moles of NO=1.

Molar conc. of NO at equilibrium =   0.4
