STUDY OF ROCKET ENGINE EXHAUST PRODUCTS
Abstract
The reaction BeO(s) + 2HF(g) yields BeF2(g) + H2O was employed to obtain values for the delta H sub f(298) and S(298) of BeF2(g). The experimentally determined values for delta H sub r and delta S sub r for the above reactions over the temperature range 943-1243 K are 20.5 ! 1.7 kcal and 6.0 ! 0.3 cal/deg/mole respectively. From these values and available thermodynamic data onALL THE SPECIES OF INTEREST, THE Second Law values for delta H sub f(298) and S(298) of BeF2(g) were found to be -191.3 ! 2.0 kcal/mole and 52.4 ! 0.3 cal/deg/mole respectively. The Third Law delta H sub f(298) for BeF2(g) was determined to be -191.2 ! 0.4 kcal/mole. (Author)
