Chapter 20: Problem 42

As mentioned in the chapter, spraying the stratosphere with hydrocarbons such as ethane and propane should eliminate \(\mathrm{Cl}\) atoms. What is the drawback of this procedure if used on a large scale for an extended period of time?

Short Answer

Expert verified
The main drawback of spraying the stratosphere with hydrocarbons on a large scale for an extended period of time is that it would contribute to global warming by producing greenhouse gases. Additionally, the production and transport of hydrocarbons could have further environmental impact, and there could be other unforeseen ecological impacts.

Step by step solution

01

Identify the process

The question refers to the process of spraying the stratosphere with hydrocarbons. When hydrocarbons like ethane and propane react with chlorine atoms, it prevents the chlorine from reacting with ozone and reduces ozone depletion.
02

Consider the drawbacks

A large-scale and prolonged application of this procedure could have negative effects. The burning of hydrocarbons produces greenhouse gases, which contribute to global warming. These gases trap heat in the atmosphere and lead to a rise in average global temperatures.
03

Consider additional drawbacks

Additionally, the production and transport of these hydrocarbons would also require energy and resources, with associated carbon emissions. There could also be other unforeseen ecological impacts of introducing large quantities of hydrocarbons into the stratosphere.

List three detrimental effects of acid rain.

Assume that the formation of nitrogen dioxide: $$ 2 \mathrm{NO}(g)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{NO}_{2}(g) $$ is an elementary reaction. (a) Write the rate law for this reaction. (b) A sample of air at a certain temperature is contaminated with \(2.0 \mathrm{ppm}\) of \(\mathrm{NO}\) by volume. Under these conditions, can the rate law be simplified? If so, write the simplified rate law. (c) Under the conditions described in (b), the half-life of the reaction has been estimated to be \(6.4 \times 10^{3} \mathrm{~min} .\) What would the half- life be if the initial concentration of NO were \(10 \mathrm{ppm} ?\)

The equilibrium constant \(\left(K_{P}\right)\) for the reaction $$ \mathrm{N}_{2}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{NO}(g) $$ is \(4.0 \times 10^{-31}\) at \(25^{\circ} \mathrm{C}\) and \(2.6 \times 10^{-6}\) at \(1100^{\circ} \mathrm{C},\) the temperature of a running car's engine. Is this an endothermic or exothermic reaction?
