Two moles of N_(2) and two moles of H_(2) are taken in a closed vessel of 5 litre capacity and suitable conditions are provided for the reaction. When the equilibrium is reached, it is found that a half mole of N_(2) is used up. The equilibrium concentration of NH_(3) is

Two moles of N_(2) and two moles of H_(2) are taken in a closed vessel

1.	Two moles of N_(2) and two moles of H_(2) are taken in a closed vessel of 5 litre capacity and suitable conditions are provided for the reaction. When the equilibrium is reached, it is found that a half mole of N_(2) is used up. The equilibrium concentration of NH_(3) is
Answer» 0.2 0.4 0.3 0.1 Solution :EQUILIBRIUM CONCENTRATION `=("No. of moles at equilibrium")/("Volume")=(1)/(5)=0.2`
