Question

The equilibrium N2 + O2 ⇔ 2NO is established 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

Answer 1

"5. Capacity of the container- 2.5L

Initial moles given are

N2- 2 moles

O2- 4 moles

Moles of N2 used in equilibrium- 0.5 moles

The equilibrium moles of NO is 2*0.5=1

The molar concentration of a solution can be found by dividing the number of moles by volume of the solution.

Thus, the molar concentration of nitric oxide is 1/2.5=0.4M/L"

Answer 2

Answer:

0.4mole ltr-1
