4. Consider the following exothermic reaction which is used as a source of O2 in some self-contained breathing devices. 4 KO2(s) + 2 CO2(g) + 2 K2CO3(s) + 3 O2(g) The above reaction is at equilibrium in a closed container. For each of the following changes, indicate whether the reaction will proceed towards products, towards reactants, or have no net reaction to reestablish equilibrium. a. CO2(g) is added b. O2(g) is removed C. Some K2CO3(s) is removed d. The temperature is increased e. The reaction is moved to a smaller vessel. f. The pressure in increased by adding N2(g) g. What general conditions of temperature and pressure favor maximum yield of O2(g)?
