Titanium - Chlorine - Oxygen - Carbon Oxidation/Reduction

Production of TiCl4: 

2  TiFeO3 (s)  + 7 Cl2 (g)  +  2  C  (s)  ---------->

2 TiCl4 (l)  + 2  FeCl3 (s)  + O2 (g)  +  CO2  (g)


& Hf  (25 C) =  -123.28  kcal/ mol

& Grxn (25 C) =  -64.14  kcal/mol

& Srxn  (25 C) =  0.20 kcal/mol K

Make Nice to Equlibrium Expression

The expression for equilibrium is read:

...........[CaCl2]^3 [CO]^3
Keq = ----------------------- = 1.449 X 10^24
............[FeCl3] [HCl]^3

Neutralization of Ferric Chloride with Aragonite

FeCl3 + 3 HCL + 3 CaCO3 -->





Fe(OH)3+ 3 CaCl2 +3 CO2







& Hrxn (25 C) = -5.776 kcals/mol







& Grxn (25 C) = -32.96 kcals/mol







& Srxn (25 C) = 0.0912 kcals/mol K
