Polymath code for example in class. Make sure you plot the instantaneous selectivity, overall selectivity and yield over time. Compare these 3 plots during the batch to understand what each of these 3 variables mean.

# ODEs
d(CA) / d(t) = -k1*CA 
d(CB) / d(t) = k1*CA - k2*CB
d(CC) / d(t) = k2*CB

# Initial conditions
CA(0) = 2 # mol/L
CB(0) = 0 # mol/L
CC(0) = 0 # mol/L

# Algebraic equations
k1 = 0.5 # 1/hr
k2 = 0.2 # 1/hr
S_DU = (k1*CA - k2*CB) / (k2*CB+1E-15)
Overall_SDU = CB/(CC+1E-15)
Yield = CB/(2 - CA+1E-15)

# Independent variable details
t(0) = 0
t(f) = 3.1  # hours
