Igcse Model Questions Vol1 2017 Chemistry Question 19
Practice objective / multiple choice question 19 from the 2017 Igcse Model Questions Vol1 Chemistry examination.
The standard enthalpies of formation at \(25^{\circ}\text{C}\) are: \(\Delta H_f^{\circ}(\text{C}_3\text{H}_8(g)) = -104.7\ \text{kJ mol}^{-1}\), \(\Delta H_f^{\circ}(\text{CO}_2(g)) = -393.5\ \text{kJ mol}^{-1}\), \(\Delta H_f^{\circ}(\text{H}_2\text{O}(l)) = -285.8\ \text{kJ mol}^{-1}\). Using these data, calculate the standard enthalpy change for the combustion of one mole of propane (\(\text{C}_3\text{H}_8\)) in oxygen to give carbon dioxide and liquid water. Write the balanced equation first, then give \(\Delta H_{comb}^{\circ}\) in \(\text{kJ mol}^{-1}\).
