- Ozone layer consists of high concentration of Ozone molecules (O3) which absorbs the harmful UV rays coming from sun and preventing the earth from its harmful effects. Ozone is considered as one of the primary greenhouse gas which absords infrared light.

- Ozone depleting chemicals such as gases containing traces of nitogen, hydrogen, chlorine and bromine are the primary accelerators of ozone depletion. Over decades, chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. ODS includes methylhalides, carbon tetrafluoride (CF4), carbon tetrachloride (CCl4), and halocarbons i.e. halons which contain bromine instead of chlorine.

- CFCs are primarily released into environment from CFC containing aerosols, refrigerators, and some kinds of foam. However, there are no natural sources of CFCs hence human kind can be blamed for the current consequences lead by CFC compacted environment and its effects.

One of the CFCs that is implicated in decreasing the ozone layer and formation of the ozone hole over Antarctica is Freon-12 or CCl2F2. Calculate the density (in g/L) of Freon-12 at STP and compare it to the average density of air. Suggest how Freon-12 can get into the stratosphere to threaten the ozone layer.

1. The effect of chlorofluorocarbons (such as CCl2F2(g)) on the depletion of the ozone layer is well known. The use of substitutes, such as CH3CH2F(g), for the chlorofluorocarbons, has largely corrected the problem. Calculate the volume (in L) occupied by 17.5 g of each of these compounds at STP. - CCl2F2(g) - CH3CH2F(g) 2. Calculate the density (in g/L) of Freon-12, CF2Cl2, at 28.6°C and 0.984 atm.

One concern about the depletion of the ozone layer is that the increase in UV light will decrease crop yields. An experiment was conducted in a green house where soybean plants were exposed to varying levels of UV levels - measured in Dobson units. At the end of the experiment the yield (kg) was measured. A regression analysis was performed with the following results: Term____|_Estimate__|_Std Error_|_t ratio_|_Prob>ltl_|_Lower 95%_|_Upper 95% Intercept__3.9800118__0.053774__74.01___<.0001___3.8638398___4.0961838 uv_______-0.046285___0.010741__*hidden__0.0008_______****hidden**** A 95% confidence interval for the mean yield when...

O3 + O -->2O2) Depletion of the ozone layer is believed to be caused by chlorine catalyzed O3 decomposition. For the uncatalyzed reaction Ea,f= 19 kJ/mol. For the following mechanism, Ea1, f =2.1 and Ea2,f =0.4 kJ/mol: Proposed Mechanism: Cl+O3--> ClO +O2 ClO+O--> Cl+O2 a.) What is the dH for the reaction? I know the answer is -390 kJ/mol. I don't know where this answer comes from! b.) What is the Ea, r for the uncatalyzed reaction? I know the...
