9. Consider the decomposition of limestone, CaCO3, represented by the equation: CaCO3(s)CaO(s)+CO2(g)H=+178.5kJ What is the effect on the equilibrium position of (a) An increase in pressure? (b) Adding a catalyst? 10. The initial step of the Ostwald process for the industrial production of nitric acid is the oxidation of ammonia to nitric oxide: 4NH3(g)+5O2(g)4NO(g)+6H2O(g)H=905.6kJ What is the effect of the equilibrium position: (a) The temperature is increased? (b) A platinum catalyst is added? (c) The pressure is increased by adding helium gas
