Colorless gas nitric oxide gas, NO, can react with oxygen to form the brown gas nitrogen dioxide, NO2, as shown below: 2NO(g)+O2(g)->2NO2(g)
Suppose you wanted to carry out this reaction in the laboratory. You could filled one gas syringe with 100 mL of nitric oxide and another with 66 mL of oxygen gas.
When you connected the syringes and mixed the gases, the reaction mixture changes to a brown color indicating the reaction occured. If the sryinges were maintains at constant temperature and pressure, what would be the expected volume of the reaction after the reaction?
