Explain how real gases differ from ideal gases. At what conditions do the variations become the biggest? At room conditions, if you know the condensation point for a series of gases, how will that allow you to predict which gases would vary most from being an ideal gas?
System were found to be [N2]=[O2]=0.200 M and [NO]=0.500 M. N2(g) + O2(g) 2NO(g) If more NO is added, bringing its concentration to [0.800 M], what will the final concentration of NO be after equilibrium is re-established?
