Question
Indicate which compound is a component of photochemical. A) NO_2 B) CO_2 C) H_2O D) SO_2 E) CO 24. In which layer(s) of Earth's atmosphere does the temperature increase with increasing altitude? i. Troposphere ii. Stratosphere iii. Mesosphere iv. Thermosphere A) NOne B) ii & iv C) i & iii D) All E) ii, iii & iv 25. The photochemical decomposition of chlorofluorocarbons, CCI_3(g) rightarrow CCI_2F(g) + CI(g), was shown to chance the decomposition of ozone, 2O_2(g) rightarrow 3O_2(g), leading to the formation of an ozone hole over the South Pole. Which of the following statements is correct for the following mechanism of the decomposition of ozone? Step 1: CI + O_3 rightarrow CIO + O_2 Step 2: CIO + O_3 rightarrow CI + 2O_2 A) CI is an intermediate CIO is a catalyst O_2 is a reaction product B) CI is an catalyst CIO is a catalyst O_2 is a reaction product C) CI is an intermediate CIO is a intermediate O_2 is a intermediate D) CI is an catalyst, CIO is an intermediate O_2 is a intermediate E) CI is a catalyt CIO is a intermediate O_2 is an intermediate 26. The photodissociation of chloroflurocarbons is the first step in the destruction of ozone in the upper atmosphere. What wavelength of light (in nm) is required to create a free CI atom? CF_2CI_2+ hv rightarrow CF_2CI + CI C - CI bond energy = 394.9 kJ/mol A) 303 B) 5.04times10^-28 C) 3.03times10^-7 D) 6.55times10^-19 E) 408Explanation / Answer
