answer the fallowing a)

b)

answer with good explanation.

For parallel reactions with two reactants (A and B), the critical factor in obtaining favorable product distribution is the contacting pattern. If both A and B are to be kept low Use a single backmix reactor with A and B added simultaneously to the reactor. O Use a plugflow reactor with A flowing continuously into the reactor and B added gradually. Use a series of backmix reactor with A and B added simultaneously to the reactor. o Use a plugflow reactor where A and B flow simultaneously to the reactor. In a series reaction where R is the intermediate and desired product: To obtain high conversion of A, a large recycle should be used. The maximum obtainable concentration of Rin a backmix reactor is higher than in a plugflow reactor. Plugflow reactor always require a smaller time than for backmix reactor to achieve maximum concentration of R. Backmix reactor gives higher fractional yield of R than in a plugflow reactor
