Question: exercise 31 calculating an equilibrium composition consider the following reaction...

Question details

Exercise 3.1: Calculating an equilibrium composition Consider the following reaction in a closed vessel at a press ature of 500°K of 1.0 atm and temper isobutane + 1-bu tene=2, 2, 3-trimethylpentane The standard Gibbs energy and enthalpy changes for this reaction at 500 K -4.10 kcal/mol,ΔΗ::-20.11 kcal/mol. are (a) Determine the equilibrium composition for this system for an intial e mixture of isobutane and butene. What assumptions did you make? (b) What is the equilibrium conversion of the reactants in part 3.1a? Assume fo economic reasons that you must increase the equilibrium conversion to 97% A, what pressure must you run this reaction at a temperature of 500 K to achieve this conversion? (c) At what temperature must you run this reaction at a pressure of 1.0 atm to achieve 97% conversion? (d) What do you know about this system that prevents you from taking these an- swers too seriously?
