Thermodynamics

Down

• 2. At a given temperature a substance its pure, most stable, form at 100 kPa. (8, 5)
• 3. The amount of heat taken in or given out at constant pressure during any physical or chemical damage. (8, 6)
• 4. A change that has a natural tendency to occur without being driven by any external influences. (11, 6)
• 5. A species that results from the homolytic fission of a covalent bond. It contains an unpaired electron, since homolytic fission results in the splitting of the electron pair in a covalent bond, one electron going to each partner. (4, 7)
• 6. The standard molar enthalpy change for the removal of an electron from a species in the gas phase to form a positive ion and an electron, both also in the gas phase. (10, 8)
• 7. The standard enthalpy change when an electron is added to an isolated atom in the gas phase. (8, 8)
