Which of the following statement is incorrect? Select all the incorrect statements, wrong choices will be penalized. The following thermochemical equation indicates that 184.8 kJ are released, if two moles of hydrogen react with nitrogen to form ammonia, N₂(g) + 3H₂(g) 2- NH3(g), AH° = -92.38 kJ. The concept of an average kinetic energy suggests that there is a range of different kinetic energies among the particles of a substance. As heat is transferred to ice cubes, its water molecules gain kinetic energy, causing the ice to melt. The first law of thermodynamics is expressed in the equation, AE = Kinetic Energy - Potential Energy. Based on the terms and symbols used in the discussions on thermochemistry, the expression, AE = AH-PAV is correct.

**Question:** Which of the following statements is *incorrect*? Select all the incorrect statements, wrong choices will be penalized. --- - \(\boxtimes\) The following thermochemical equation indicates that 184.8 kJ are released, if two moles of hydrogen react with nitrogen to form ammonia. \( \text{N}_2(g) + 3\text{H}_2(g) \rightarrow 2\text{NH}_3(g), \, \Delta H^\circ = -92.38 \, \text{kJ} \). - \(\boxtimes\) The concept of an average kinetic energy suggests that there is a range of different kinetic energies among the particles of a substance. - \(\boxtimes\) As heat is transferred to ice cubes, its water molecules gain kinetic energy, causing the ice to melt. - \(\boxtimes\) The first law of thermodynamics is expressed in the equation, \(\Delta E = \text{Kinetic Energy} - \text{Potential Energy}\). - \(\boxtimes\) Based on the terms and symbols used in the discussions on thermochemistry, the expression, \(\Delta E = \Delta H - P \Delta V\) is correct.
