One liter per minute of liquid containing A and B (CA0 = 0.10 mollliter, CB() = 0.01 mollliter, Cco=0) flow into a mixed reactor of volume V = 1 liter. The materials react in a complex manner for which the stoichiometry is unknown. The outlet stream from the reactor contains A, B, and C (CAf = 0.02 mollliter, CBf = 0.03 mollliter, Cci = 0.04 mollliter), as shown in fig. 


Find the rate of reaction of A, B, and C for the conditions within the reactor  mol/liter.min
