Question

Predict the shift in the equilibrium position that will occur for each of the following reactions when the volume of the reaction container is increased. N_2(g) + 3H_2(g) 2NH_3(s) PCl_5(g) PCl_3(g) + Cl_2(g) H_2(g) + F_2(g) 2HF(g) COCl_2(g) CO(g) + Cl_2(g) CaCO_3(s) CaO(s) + CO_2(g) An important reaction in the commercial production of hydrogen is CO(g) + H_2O(s) H_2(g) + CO_2(g) How will this system at equilibrium shift in each of the five following cases? Gaseous carbon dioxide is removed. Water vapor is added. In a rigid reaction container, the pressure is increased by adding helium gas. The temperature is increased (the reaction is exothermic). The pressure is increased by decreasing the volume of the reaction container. What will happen to the number of moles of SO_3, in equilibrium with SO_2 and O_2 in the reaction 2SO_3(g) 2SO_2(g) + O_2(g) in each of the following cases? Oxygen gas is added. The pressure is increased by decreasing the volume of the reaction container. In a rigid reaction container, the pressure is increased by adding argon gas. The temperature is decreased (the reaction is endothermic). Gaseous sulfur dioxide is removed. In which direction will the position of the equilibrium 2HI(s) H_2(g) + I_2(g) be shifted for each of the following changes? H_2(g) is added. I_2(g) is removed. HI(g) is removed. In a rigid reaction container, some Ar(g) is added. The volume of the container is doubled. The temperature is decreased (the reaction is exothermic). Hydrogen for use in ammonia production is produced by the
