Answer:
Explanation:
Hello,
By considering the rate law:
![ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\](https://tex.z-dn.net/?f=ln%28%5Cfrac%7B%5BCO_2%5D%7D%7B%5BCO_2%5D_0%7D%20%29%3D-kt%5C%5C)
Solving for the time, we've got:
![k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\ \\k=1.12x10^{-4}s](https://tex.z-dn.net/?f=k%3D-%5Cfrac%7Bln%20%28%5Cfrac%7B%5BCO_2%5D%7D%7B%5BCO_2%5D_0%20%7D%29%7D%7Bt%7D%5C%5C%5C%5Ck%3D-%5Cfrac%7Bln%28%5Cfrac%7B56.0mmol%2Adm%5E%7B-3%7D%20%7D%7B220mmol%2Adm%5E%7B-3%7D%20%7D%29%7D%7B1.22x10%5E%7B4%7Ds%20%7D%5C%5C%20%20%5C%5Ck%3D1.12x10%5E%7B-4%7Ds)

Answer:
Presence of water molecules
Explanation:
Temperature decreases with an increase in altitude. At sufficiently high altitudes, the air is much colder than the air on the surface of the Earth. Water vapor has a low density and is capable to rise until it gets into a medium with a significantly low temperature and pressure to condense and produce water droplets out of water vapor. Those droplets then form clouds.
