Pure iron can be obtained from naturally found iron (III) oxide, Fe2​O3​, as shown in reaction equation below: Fe2​O3​( s)+3CO(g)⇌2Fe(s)+3CO2​( g) Based on the reaction: (i) Write the equilibrium constant equation. (ii) Is the reaction heterogeneous OR homogeneous? (ii) GivenK pp​ of this reaction is 12.19 at a temperature of 29∘C. Determine Kc​ of the reaction. (1+1+2 marks ) The reaction below is carried out to produce sulphur dioxide, SO2​. At equilibrium, 1.67 mole of H2​ S and 2.35 mol of O2​ were measured inside a 1 L reaction chamber. The equilibrium constant, Kc​, is 1.7×10−3. 2H2​ S( g)+3O2​( g)⇌2H2​O(g)+2SO2​( g) Given that the reaction produce the same amount of water vapour and sulphur dioxide gas at equilibrium: (i) Determine the concentration of water vapour and sulphur dioxide at equilbrium. (ii) Determine the Kc​ value for this reaction: 3H2​O(g)+3SO2​( g)⇌3H2​ S( g)+29​O2​( g) (3+2 marks ) Chlorous acid, HClO2​, is a weak acid with pK2​ of 1.96.A combination of HClO with
