The Haber process is an important reaction for the fixation of nitrogen, nitrogen is converted into ammonia, an important component in the production fertilizers. N2(g) + 3H2 = 2NH3(g) + 22,000cal. Consider the reaction is at equilibrium. Explain in which direction the equilibrium is shifted when: A) more nitrogen is added? B) more hydrogen is added? C) ammonia is removed? D) the reaction is cooled?
CaCO3(s) CaO(s) + CO2(g) H°rxn = 175 kJ How will the amount (not concentration) of CaCO3(s) change with the following stresses? CO2(g) is removed. CaO(s) is added. The temperature is increased. The volume of the container is decreased.
