Question #234278

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.

Expert's answer

For this first reaction, we can observe that there is a 2:1 ratio for NO_{3} and NO_{2.}

It is evident that NO is produced in two separate occasions in the process of consuming NO_{3.}

Therefore, if the rate of consumption of NO_{3 } is 2.2 x10^{5}

Then: 1/5 the rate of production of O_{2 } gives us 4.4 x10^{5}

The conversion if the recycle is shut off:

The proceeding reaction would be as follows:

O_{2: }NO_{3 } is 2: 1

NO_{3 }is consumed at the rate of rate of 2.3 mill per minute

Product of O_{2 } would also be 2.3 per minute

The conversion would be 2.3 per mil per minute
