Text: Why may the debt crisis be only "sleeping," rather than "dead?" Hint: Debt restructuring has postponed but not eliminated the need for eventual repayment, and a small share of debt has actually been written off. It remains to be seen whether indebted economies have reformed sufficiently and that they will operate in an economic climate that enables the debts to be repaid [1/2 page, 50 points].

1. Consider a catalyst particle of radius R. This particle is in a catalytic reactor, where it is submerged in a gas stream containing the reactant A and product B. In the neighborhood of the surface of the particular catalyst particle under consideration, the concentration is CA0. Species A diffuses through the pores of the catalyst and form product B on the catalyst surface. If the reaction is of second order, find the Concentration profile of reactant A, Thiele Modulus and Effectiveness factor. Rework on the same problem by assuming reaction is of zero order. Compare both the Thiele Modulus and effectiveness factor profile. Which one will be more limited to the diffusional resistance.
