The irreversible gas-phase reaction A + B ----> C is carried out in an isothermal (400 C) constant-pressure (1 atm) batch reactor in the presence of inerts (I). The initial gas composition in mole fractions is given by yA0 = 0.40; yB0 = 0.40; yC0 = 0.10; yI = 0.10. The reaction is first-order both in A and in B with a rate constant, k = 3.46 x10-2 dm3mol-1 s-1 at 400 C.

(a) Set up a stoichiometric table.

(b) Determine the time it will take for yC to reach 0.20.
