Document Summary

The exam is 100 points total and 20% of the course grade. Please read through the questions very carefully before answering. You are allowed one 8. 5 "x 11 sheet of paper and a calculator for this exam. A list of (possibly) useful integrals is provided on the last page of this exam. Consider a non-isothermal liquid-phase batch reactor initially charged with inert solvent and reagent a, which reacts according to zero-order kinetics to yield product b in the exothermic reaction a b. Please make sure to read all parts of this question, and clearly show your reasoning. U = overall heat transfer coefficient (w/m2 k) A = heat transfer area available in reactor (m2) H0 rxn = standard-state enthalpy change of reaction per mole of a reacted < 0. Cp = same molar heat capacity for all species in reactor including inert solvent (j/mol k) Na0 = initial amount of a charged to reactor (moles)
