At present the conversion is 66.7% for the elementary second order reaction 2A→2R when operating in an isothermal plug flow reactor with a recycle ratio of unity. Determine the conversion if recycle is shut off.
For this first reaction, we can observe that there is a 2:1 ratio for NO3 and NO2.
It is evident that NO is produced in two separate occasions in the process of consuming NO3.
Therefore, if the rate of consumption of NO3 is 2.2 x105
Then: 1/5 the rate of production of O2 gives us 4.4 x105
The conversion if the recycle is shut off:
The proceeding reaction would be as follows:
O2: NO3 is 2: 1
NO3 is consumed at the rate of rate of 2.3 mill per minute
Product of O2 would also be 2.3 per minute
The conversion would be 2.3 per mil per minute
