10. Solving a chemistry problem

62 (d, e, f). For a reversible reaction SO2(g) 1/2O2(g) ↔ SO3(g) H0298 = -95.6 kJ answer the questions:
d) how will the concentration of oxygen change with increasing temperature;
e) where will the equilibrium shift with an increase in the volume of the reaction vessel;
f) Will the introduction of a catalyst into the reaction mixture affect the equilibrium concentration of sulfur trioxide?
