The following problems are straightforward gas-phase equilibria problems. When you are done with each problem close the window to return to this menu.

• Problem (1): NO_{2 (g)} N₂O_{4 (g)} (unbalanced)
  
  
• Problem (2): SO_{2 (g)} + O_{2 (g)} SO_{3 (g)} (unbalanced)
  
  
• Problem (3): C_(s) + H₂O_(g) CO_(g) + H_{2 (g)}
