Use the References to access important values if needed for this question. The compound benzene, C6H6, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved is 2 C6H₁(!) + 15 O₂(g) 12 CO₂(g) + 6 H₂O(g) The standard enthalpy of formation of liquid benzene at 25 °C is 49.0 kJ mol-¹; other relevant enthalpy of formation values in kJ mol-¹ are: CoH6(g) = 82.9 ; CO2(g) = -393.5; H2O(g) = -241.8 (a) Calculate the enthalpy change in the burning of 5.000 mol liquid benzene to form gaseous products at 25°C. State explicitly whether the reaction is endothermic or exothermic. ΔΗ° = kJ (b) Would more or less heat be evolved if gaseous benzene were burned under the same conditions?
