# Board & Competitive Exams 12. Two moles of N, and two moles of H, are taken in a closed vessel of 5 litres capacity and suitable conditions are provided for the reaction. When the equilibrium is reached, it is found that a half mole of NA is used up. The equilibrium concentration of NH, is (1) 03 (3) 02 (2) 04 (4) 0.1
