1. A CSTR and a PFR of equal volume (VCSTR = VPFR = V) are used to degrade a compound in a first-order manner under steady-state conditions.
(a) If the CSTR gives a 80% degradation what is the efficiency of the PFR?
(b) If instead of one CSTR of volume V, you use 5 CSTRs in series, each having a volume of 0.2V, what would be the overall degradation efficiency?
(c) Show that the overall efficiency will be equal to that of the PFR (volume V) if you use an infinite number (n→∞) of CSTRs in series each having a volume of V/n.

1) Contract Law - Insurance
Mario has purchased a new kart, and would like to get some insurance on it. The kart is
worth $1,000, and there is a 10% chance he will be in an accident and do $500 worth of
damage to his kart. Mario's utility function is U(V) = ln(V), where V is the value of his
kart.
a) Calculate Mario's expected utility with no insurance.
b) Now suppose Mario can buy auto insurance from Yoshi for a premium of $I that will completely compensate him for his $500 loss if it occurs. Find an expression Mario's
expected utility with insurance.
c) What is the most Mario is willing to pay for insurance?
d) Repeat steps a) - c) with a utility function of U(V) = V. Comment on why any differences are present in willingness to pay for insurance.
