Reactant A decomposes in an isothermal batch reactor (C_A0 = 100) to produce wanted R and unwanted S, and the following progressive concentration readings are recorded:

Additional runs show that adding R or S does not affect the distribution of products formed and that only A does. Also, it is noted that the total number of moles of A, R, and S is constant.

(a) Find the φversus C_A curve for this reaction. With a feed of C_A0 = 100 and C_Af = 10, find C,

(b) From a mixed flow reactor,

(c) From a plug flow reactor,

(d) And (e): Repeat parts (b) and (c) with the modification that C_A0 = 70.
