Question #249155

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.

Solve this problem with step by step process?

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
