7.9 Nitric oxide reacts with Br2 and gives nitrosyl bromide as per reaction given below:
When 0.087 mol of NO and 0.0437 mol of Br2 are mixed in a closed container at a constant temperature, 0.0518 mol of NOBr is obtained at equilibrium. Calculate the equilibrium amount of NO and Br2 .
The initial concentration of and is 0.087 mol and 0.0437 mol resp.
The given chemical reaction is-
Here, 2 mol of produces from 2 mol of . So, 0.0518 mol of is obtained from 0.518 mol of .
Again, From 1 mol of two mol of produced. So, to produce 0.518 mol of we need mol of .
Thus, the amount of present at equilibrium = 0.087 - 0.0518 = 0.0352 mol
and the amount of present at the equilibrium = 0.0437-0.0259 = 0.0178 mol
