The elementary gas-phase reaction2A → Bis carried out in a constant-volume batch reactor where 50% conversion is achieved in 1 hour. Pure Ais charged to the reactor at an initial concentration of 0.2 mol/dm3. If the same reaction is carried outin a CSTR, what volume would be necessary to achieve 50% conversion for a feed molar flow rate of500 mol/h and an entering concentration of A of 0.2 mol/dm3? (Ans.:V = 5,000 dm3

Explanation:

Hello,

In this case, for the STR reactor carrying out this chemical reaction, the material balance is:

Thus, with the given information we compute the rate constant as follows:

Now, for the CSTR we have the following design equation in terms of conversion for finding the volume:

Therefore, it turns out:
