Players ‘bounce’ back if they roll too high and must continue playing. Lab Spill Skip a go Decrease Volume ⇄ Add Products ⇄ Decrease temperature ⇄ FINISH Backwards Equilibrium Theory behind the game: Le Chatilier States: If a reaction is exposed a change it will move in the direction that will oppose this change. if I..... INCREASE Temperature Pressure Volume Reactants Product endothermic less particles more particles forward reverse if I..... Decrease Temperature Pressure Volume Reactants Products exothermic more particles less particles reverse forward Equilibrium Equilibrium reaction card reaction card N2(g) + 3H2(g) ⇄ 2NH3(g) ΔH = -’ve 2H2O(l) ⇄ H3O+(aq) + OH-(aq) ΔH = +’ve The Haber Process Self Ionisation of water Equilibrium Equilibrium reaction card reaction card CH4(g) + H2O(g) ⇄ CO(g) + 3H(g) ΔH = +’ve COOH(aq) ⇄ H+(aq) + COO-(aq) ΔH = -’ve Steam Reforming Ionisation of methanoic Equilibrium Equilibrium reaction card reaction card CO(g) + H2O(g) ⇄ CO2(g) + H2(g) ΔH = -’ve 2NO2(g) ⇄ N2O4(g) ΔH = -’ve Water Gas Shift reaction Cut out these reaction carts Equilibrium Equilibrium reaction card reaction card Fe3+(aq) + SCN-(aq) ⇄ FeSCN2+(aq) ΔH = -’ve CH2CH2(g) + H2O(g) ⇄ C2H5OH(g) ΔH = +’ve Iron thiocyanate equilibrium Formation of ethanol from ethene Equilibrium Equilibrium reaction card reaction card N2(g) + O2 (g) ⇄ 2NO(g) ΔH = +’ve 2SO2(g) + O2(g) ⇄ 2SO3(g) ΔH = -’ve Formation of Nitrous Monoxide Oxidation of sulphur dioxide Equilibrium Equilibrium reaction card reaction card PCl3(g) + Cl2(g) ⇄ PCl5(g) ΔH = +’ve H2O(l) ⇄ H2O(g) ΔH = +’ve Evaporation of water Cut out these reaction carts
