The irreversible gas-phase non-elementary reaction A + 2B ---> C takes place in an isothermal (227 C) constant-volume batch reactor. The initial feed to the reactor consists of 40 mol% A and 60 mol% B at a total pressure of 10 atm. Measurements of the rate of reaction as a function of conversion yielded the following results:

-rA (mol dm^-3 s^-1) x (1x10^8)

 0.010 0.005 0.002 0.001

XA  

 0.0 0.2 0.4 0.6

Calculate the time required to achieve a conversion of A of 30%.
