57.) The ozone, O3, of the stratosphere can be decomposed by reac- tion with nitrogen oxide (commonly called nitric oxide), NO, from high-flying jet aircraft. O3(g) + NO(g) → NO2(g) + O2(g) The rate expression is rate = k[O3][NO]. Which of the following mechanisms are consistent with the observed rate expression? (a) NO + 03 - NO3 + 0 (slow) NO3 +0 - NO2 + O2 (fast) O3 + NO → NO2 + O2 overall (b) NO + O3 ->...

Special Order Flying High Airlines needs a special order of 500,000 gallons of jet fuel from Energy Source, a local supplier which Flying High usually does not do business with. Due to winter weather and poor travel conditions, Flying High's regular shipment of fuel did not arrive. Flying High usually pays $4.50 per gallon under contract with their regular supplier and is not willing to pay Energy Source any more than that. Energy Source is a smaller producer and usually...

1. (40) Consider a F-16 fighter jet flying at 40,000 ft (Pa,= 17.2kPa,7a -51°C, Ka = 1.4, Ra = 287 J/kgK) while traveling at subsonic speed. The gases from the engine can be considered as ideal gas with x = 1.33, R = 287 px. Now suppose the pilot needs to rapidly accelerate so that he/she calls for maximum thrust. A number of things will happen simultaneously as the throttle is increased: a. The engine rotational speed increases so that...
