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

Enzyme activity was monitored over the last two stages of an enzyme extraction-separation process. 0.4 g protein, from Stage 5, converted 46 mmol substrate in 10 sec, and 0.02 g protein, from Stage 6, converted 49 mmol in 30 sec. Calculate the specific activities in units/g at each of the two steps
