The emission of NO, by fossil fuel combustion can be prevented by injecting gaseous urea into the combustion mixture. The urea reduces NO (which oxidizes in air to form NO2) according to the reaction: 2 CO(NH;)»(3) + 4 NO(3) + O2(8) 4 Na(8) + 2 CO;(g) + 4 H¿O(g) Suppose that the exhaust stream of an automobile has a flow rate of 2.55 L/s at 655 Kand contains a partial pressure of NO of 12.4 torr. What total mass of urea is necessary to react complete- ly with the NO formed during 8.0 hours of driving?

A large sport utility vehicle has a mass of 2500 kg.Calculate the mass of CO2 emitted into the atmosphere upon accelerating the SUV from 0.0 mph to 65.0 mph. Assume that the required energy comes from the combustion of octane (C8H18) with 30% efficiency. (Hint: Use KE = ½ mv2 to calculate the kinetic energy required for the acceleration and pay attention to units).
Anna was asked to identify and explain if the equation CO2 (1)-CO2 (g) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been? Anna's statement : The equation is an endothermic reaction because the energy is released from gaseous CO2 to the surroundings to become liquid CO2 causing the molecules to slow down. earch a inse # % & 3 4 7 8 9 E R Y P D G H J L V BN M alt
