The following reversible gas-phase reaction is carried out in a
10 L batch reactor.
A <->C -rA = CA – 0.5CC [mol/(L h)]
Determine the pressure, temperature, and gas phase composition
(mole fractions) in the reactor after 1
hour of operating adiabatically given the following initial
conditions and physical properties and the
assumption of ideal gas behavior:
P0 = 100 kPa, yA0 = 0.5, yC0 = 0.1, yinert=0.4, T0 = 500 K.
cpA = cpC = 10 J/mol K, cpinert = 5 J/mol K, HR(298K) = -20 kJ/mol

An elementary irreversible gas-phase reaction, A -> 2B, is
taking place in an isothermal batch reactor. Assume ideal gas
behavior for both species. Initially, the reactor contains only the
reactant A at a pressure of 5.0 atm, a volume of 20.0 L, and a
temperature of 400 K. The rate constant at this temperature is 0.25
min-1. Find the time required for the concentration of A
to drop below 5% of its initial value in these two scenarios:
