Compound A is converted to B in a CSTR. The reaction rate is first-order with a reaction rate constant of 20 min-1. Compound A enters the reactor at a flow rate of 12 m3/min (concentration of 2.0 kmol/m3). The value of the product B is $1.50 per kmol and the cost of reactor operation is $2.50 per minute per cubic meter. It is not economical to separate unconverted A to recycle it back to the feed.
