Homework 19: Methyl trichlorosilane (gas) dissociates into Silicon Carbide (solid) and Hydrogen Chloride (gas) according to the reaction: CH3C13Sig) = SiC(s) + 3HCl(g) Given the data below, and assuming that the heat of reaction is constant with temperature, what is the equilibrium gas phase composition at: (a) 298K and 1 bar (b) 1200K and 200 bar G24 Bii (second virial constant at 1200K) Component (J/mol) (J/mol) (cm3 /mol) CH3C13Si(g) -468,020 -528,860 10 SiC(s) -69,138 -71,550 N/A HCl(g) -95,299 -92,307 -165 You may assume d12 is negligible in these calculations. Assume 1 mole of CH3C13Si is fed to the system and initially there is no SiC or HCl. -0,298 ,298
