Edexcel IAL Chemistry AS 6.1 Enthalpy change and standard conditions
Check temperature and pressure against the standard values before deciding whether the measured energy change can be reported as a standard molar enthalpy.
How this is tested
- State standard enthalpy conditions as 298 K and approximately 100 kPa pressure.
- Explain why non-standard temperature data cannot give a standard molar enthalpy.
