SO2 + NO2 ⇌ SO3 + NO 5.1.1 Write out the Kc expression for this reaction? (2) 5.1.2 Calculate the equilibrium constant at this temperature if the moles of NO(g) at equilibrium is found to be 0,02. (5) 5.2 Consider the equilibrium between the hydrogen sulfate ion and water: HSO4 – (aq) + H2O(l) ⇌ SO4 2- (aq) + H3O+ (aq) 5.2.1 When the temperature is decreased, the pH of the solution decreases. Use this information to deduce whether the forward reaction is exothermic or endothermic. Explain according to Le Chatelier’s Principle. (4) 5.2.2 Calculate the concentration of OH- ions in the aqueous equilibrium mixture if the concentration of H3O+ ions at 25˚C is 2,5 x 10-3 mol.dm-3. (3) 5.3 Consider the reaction in a closed system: H2(g) + I2(g) ⇌ 2HI(g) (
