Briefly describe the absorption of solar radiation in the stratosphere by \(\mathrm{O}_{2}\) and \(\mathrm{O}_{3}\) molecules.
The molar heat capacity of a diatomic molecule is \(29.1 \mathrm{~J} / \mathrm{K} \cdot \mathrm{mol} .\) Assuming the atmosphere contains only nitrogen gas and there is no heat loss, calculate the total heat intake (in kilojoules) if the atmosphere warms up by \(3^{\circ} \mathrm{C}\) during the next \(50 \mathrm{yr}\). Given that there are \(1.8 \times 10^{20}\) moles of diatomic molecules present, how many kilograms of ice (at the North and South Poles) will this quantity of heat melt at \(0^{\circ} \mathrm{C} ?\) (The molar heat of fusion of ice is \(6.01 \mathrm{~kJ} / \mathrm{mol} .)\)
The balance between \(\mathrm{SO}_{2}\) and \(\mathrm{SO}_{3}\) is important in understanding acid rain formation in the troposphere. From the following information at \(25^{\circ} \mathrm{C}\) $$ \begin{aligned} \mathrm{S}(s)+\mathrm{O}_{2}(g) & \rightleftharpoons \mathrm{SO}_{2}(g) & K_{1} &=4.2 \times 10^{52} \\ 2 \mathrm{~S}(s)+3 \mathrm{O}_{2}(g) & \rightleftharpoons 2 \mathrm{SO}_{3}(g) & K_{2} &=9.8 \times 10^{128} \end{aligned} $$ calculate the equilibrium constant for the reaction $$ 2 \mathrm{SO}_{2}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{SO}_{3}(g) $$
