Question

C3H3 (g) + 5 02 (g) 3 CO2 (g) + 4 H20 (8)
The standard enthalpies of formation of CO2 (g) and H20 (8) are - 4.00 x 102 kJ/mol and - 2.90 x 102 kJ/mol, respectively. When 11.2 L CO, (g) at STP is formed via the
given reaction, 350 kj of heat is released.
Which of the following statements is/are false for this reaction?
1. The standard enthalpy of formation of C3H3 (g) is - 260 kJ/mol.
II. 232 kJ of heat is released when 14.4 g H2O (e) is formed via the given equation.
II. When this reaction is carried out at constant pressure and temperature, work is done by the reacting system on the surroundings.
