At high temperatures, nitrogen (N\({}{2}\)) and oxygen (O\({}{2}\)) gases react to form nitric oxide (NO) in a highly endothermic process. In a closed vessel, the three compounds form an equilibrium [ee-kwuh-LIB-ree-uhm]. Which of the following changes to the vessel will result in the production of more NO?

W) Addition of helium at constant volume

X) Adding a catalyst

Y) Increasing the temperature of the vessel

Z) Removing oxygen from the vessel
Y) INCREASING THE TEMPERATURE OF THE VESSEL
