Platinum (Pt) is used in part of your car's catalytic converter to reduce carbon monoxide emissions by the following chemical reaction: 2CO(g) + O2(g) Pt 2CO2(g) --->

1) A matrix contains 6.5mg Pt/g of matrix. What is the %Pt in the matrix by mass?

2) Using this platinum catalyst, you want to create a catalytic system for an automobile so it can handle the following requirements:

A) When accelerating, the automobile engine produces 168 L/s of exhaust gases. CO is present at about 1.6 mg CO per 1 L exhaust before passing through your catalyst matrix. You want the catalytic converter to convert all of the CO(g) to CO2(g) before passing it through the rest of the exhaust system. How many grams of CO will pass through your catalytic matrix per minute?

B) When operating properly, each gram of Pt can react 2.6 g of CO each minute. How many g of Pt catalyst will you need? How many g of matrix will be necessary to contain this amount of Pt?

C) The matrix has a high surface area (240 m2/g matrix) to allow exhaust gases to contact as much Pt as possible. How much surface area will this much catalyst matrix have?

D) The catalyst matrix has a density of 0.81 g/mL. What volume of catalytic matrix is needed to reduce CO emissions?

E) What if you were designing an engine for a SUV that produced 2.40 × 102 L/s of exhaust with a CO content of 1.9 mg CO per 1L of exhaust? What volume of catalytic matrix would you need to reduce the CO emission in this automobile?
