If 0.0791 ft3 SO2, 0.158 ft3 NO2, 0.0791 ft3 NO, and 0.119 ft3 SO3 (all at STP) are transferred to a 1.32 gal reaction vessel and heated to 733 K, determine the following:
a)
The initial reactor pressure in atm
b)
The equilibrium molar concentrations (in mol L–1) of each substance
c)
The equilibrium reactor pressure in atm
