Question
Oxygen gas can be converted into ozone gas (O3) by lightning or electrical sparks according to the following UNBALANCED reaction: 68 kcal + O2(g) O3(g) + 31 kcal a. Rewrite the reaction in a balanced form. b. Indicate the direction (fwd, reverse, or no change) the reaction will proceed if the following occur: Increasing the pressure of the reaction Decreasing the amount of O2(g) ______ Decreasing the temperature of the reaction Addition of a catalyst Increasing the amount of O3(g) Iron (III) oxide reacts with carbon monoxide to produce iron and carbon dioxide according to the following UNBALANCED reaction: Fe2O3(g) + CO(g) Fe(s) + CO2(g) + 212 Kcal a. Rewrite the reaction in a balanced form. b. Write the correct equilibrium expression (Keq) for the balanced reaction. c. Indicate the direction (fwd, reverse, or on change) the reaction will proceed if the following occur: Decreasing the pressure of the reaction Increasing the amount of CO(g) Decreasing the amount of CO2(g) Decreasing the temperature of the reaction
Explanation / Answer
a)
3O2(g)<.....>2O3(g) -37Kcal
b)
forward reaction takesplace
backward reaction takesplace
backward reaction takesplace
it brings the reaction to eq. rapidly
backward reaction takesplace
2)
a)
Fe2O3(g) +3CO(g) <............> 2Fe(S) + 3CO2(g) +212 Kcal
b)
Keq = [CO2]^3 /[CO]^3 [Fe2O3]
c)
backward reaction takesplace
forward reaction takesplace
forward reaction takesplace
Forward reaction takesplace
