Vedclass · Answer

(D) According to the environmental chemistry data regarding global warming,the contribution of $CFCs$ (chlorofluorocarbons) to global warming is approximately $14\%$ to $15\%$,while the contribution of ozone is negligible or significantly lower in comparison. Based on standard textbook values,the contribution of $CFCs$ is considered to be $14\%$ or $15\%$. Therefore,$15\%$ is the most appropriate answer among the given options.

List-$I$	List-$II$
$(a)$ $2 SO_{2(g)} + O_{2(g)} \rightarrow 2 SO_{3(g)}$	$(i)$ Acid rain
$(b)$ $HOCl_{(g)} \stackrel{h \nu}{\longrightarrow} \dot{O}H + \dot{Cl}$	$(ii)$ Smog
$(c)$ $CaCO_{3} + H_{2}SO_{4} \rightarrow CaSO_{4} + H_{2}O + CO_{2}$	$(iii)$ Ozone depletion
$(d)$ $NO_{2(g)} \stackrel{h \nu}{\longrightarrow} NO_{(g)} + O_{(g)}$	$(iv)$ Tropospheric pollution

What is the percentage contribution of $CFCs$ to global warming compared to ozone (in $\%$)?
