The irreversible elementary reaction 2A > B takes place in the gas phase in an isothermal tubular reactor. The feed is one mole of A per one mole of C, an inert. The entering temperature and pressure are 427°C and 10 atm, respectively. The gas constant R = 0.08206 atm · L/mol · K.
(a) Determine the concentration of A at the entrance to the reactor.
(b) If CA0 = 1.0 mol/L, what is the concentration of A at 90% conversion of A?

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:

The reactor is initially charged with a stoichiometric ratio of A
and B. The reaction is moderately exothermic and the heat of
reaction will be removed via cooling water. The following data is
available:

A gas phase reaction takes place in a syringe at a constant
temperature and pressure. If the initial volume before reaction is

that you start with stoichiometric amounts of the reactants, the
reaction goes to completion and that the gases behave ideally.)
