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. The concentration of NO and Br2 at equilibrium will be:
1. NO = 0.0352 mol; = 0.0178 mol
2. NO = 0.352 mol; = 0.178 mol
3. NO = 0.0634 mol; = 0.0596 mol
4. NO = 0.634 mol; = 0.596 mol
