The variation of concentration of C O 2 in a large city should be predicted on the basis of given average concentration value of carbon dioxide. Concept introduction: Carbon dioxide is one of the major anthropogenic greenhouse gases and its concentration on a large scale, all over the world makes harmful effect to the earth and to the living systems on earth. Its concentration varies in accordance with the changes in season and climate in a particular area. Large increase in the number of automobiles, also enhance the concentration of carbon dioxide in a great extent. Parts per million (ppm): It is one of the important concentration expressing terms, and which describes grams of solute per million grams of total solutions. ppm = Mass of solute Mass of solution ×10 6

Question

A large sport utility vehicle has a mass of 2.5 * 103 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 with 30% efficiency. (Hint: Use KE = 1/2 mv2 to calculate the kineticenergy required for the acceleration.)

Interpretation Introduction

Interpretation:

The variation of concentration of CO2 in a large city should be predicted on the basis of given average concentration value of carbon dioxide.

In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?

Carbon dioxide emissions associated with a one-night stay in a hotel room are calculated at 29.53 kg of CO2 per room day for an average hotel. The 200 rooms of your hotel are all occupied for two days during a college football game. How much CO2 did the guests and hotel release into the atmosphere?
