1. Consider the balanced equation below the system is at equilibrium and the production of carbon dioxide and water are favored over the reverse reaction.

CH₃CH₂OH_(s) + 3O_2(g) 2CO_2(g) + 3H₂O_(l) H = 1,199 kJ/mol

• What type of chemical reaction is this (synthesis, combustion, single displacement, double displacement, decomposition or redox)? Why do you say so?
• If more oxygen is added, how will the reactions shift to reestablish equilibrium? How do you know?
• If water is added, how will the reactions shift to reach equilibrium again? How do you know?
• If heat is added to this system, how will the reactions shift? How do you know?
• Name and explain (in your own words) the principle that helps you predict each of these shifts in equilibrium.
