Question 53

In a catalytic converter, carbon monoxide gas reacts with nitrogen monoxide gas to reduce toxic emissions according to the following equation:

2\text{CO(g)} + 2\text{NO(g)} \rightarrow 2\text{CO}_2\text{(g)} + \text{N}_2\text{(g)}

If 180 cm³ of nitrogen monoxide gas reacts completely with an excess of carbon monoxide, what is the total volume of gaseous products formed? (Assume all gas volumes are measured at the same temperature and pressure.)
