At a particular temperature a 2.00-L flask at equilibrium contains 2.80 x10⁻4 mol N₂, 2.50 x 10⁻5 mol O₂, and 2.00 x 10⁻2 mol N₂O. Calculate K at this temperature for the reaction
2N₂(g) + O₂(g) (------)2N₂O(g)
If [N₂] =2.00 x 10⁻4M, [N₂O] =0.200M, and [O₂]= 0.00245M, does this represent a system at equilibrium?
