Consider the following set of reactions:
1. C+B → A -rB = 1000 exp(-12,800 K/T)Cc^2CB
2. A + B =D -r2B = 10 exp(-8,000 K/T)CA^2 CB
3. A + B + U -r3B = 100 exp(-1,000 K/T)CA CB^3
Required:
a. Determine the net rates of reaction for species A and B.
b. Calculate the instantaneous selectivity of D over U in terms of temperature and species concentrations.
c. Compare selectivities of D over U at 300 K and 1000 K.
d. Propose different reactor configurations and conditions to maximize the selectivity of D.
