Thermodynamics of thermal hydrogenation reactions?

2011-07-05View Original

Thread Content

Thermal hydrogenation: SiCl4 + H2 → SiHCl3 + HCl. How much heat is generated when 1 mole of TCS is produced? Does that big shot know?

Heat is related to reaction temperature and pressure.

Reply to 2# Hidden Pig: The reaction heat is independent of pressure and is only a function of temperature, unless a change in pressure causes a phase transition within that temperature range

The original poster should go through a textbook on physical chemistry and look at the methods for calculating reaction enthalpy changes. Under standard conditions, the reaction enthalpy can be calculated by direct lookup; however, for the enthalpy changes caused by temperature variations, isobaric temperature variation methods can be used.
