Nitric oxide reacts with ${{Br}_{2}}$ and gives Nitrosyl Bromide as per reaction given below:

Nitric oxide reacts with {{Br}_{2}} and gives Nitrosyl Bromide as per reaction given below:

When 0.087 moles of NO and 0.0437 moles of {{Br}_{2}} are mixed in a closed container at a constant temperature, 0-0518 moles of NOBr is obtained at equilibrium. Calculate equilibrium amount of NO and {{Br}_{2}}.

At equilibrium 0.0518 moles of NOBr are formed, then 0-0518 moles of NO and 0.0518/2 moles of${{Br}_{2}}$ would have reacted.
