Arthropods invaded land about 100 million years before vertebrates did so. This most clearly implies that

#Section 6: Plant, Animal and Microbial Biotechnology
  1. arthropods have had more time to co-evolve with land plants than have vertebrates.
  2. extant terrestrial arthropods are better adapted to terrestrial life than are extant terrestrial vertebrates.
  3. ancestral arthropods must have been poorly adapted to aquatic life, thus experienced a selective pressure to invade land.
  4. vertebrates evolved from arthropods.

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
