Question

1. The irreversible reaction

k

A --------> B

is carried out in a reactor that initially contains 1.5 m3 of solution with a concentration of 1 kmol of A per cubic meter of solution. A solution containing 0.50 kmol of A/m3 enters the tank at a rate of 10 m3/h and is mixed perfectly with the existing solution. If the resulting product solution leaves the reactor at 5.0 m3/h, obtain an expression for concentration of A as a function of time. The reaction is first order with k = 0.2 hr^-1. Calculate the concentration of A after (a) 0.2 hr and (b) 1.0 hr. (Ref.2)
