Answer:

$k=1.12x10^{-4}s$

Explanation:

Hello,

By considering the rate law:

$ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\$

Solving for the time, we've got:

$k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\ \\k=1.12x10^{-4}s$

Best regards.

nata0808 [166]

Answer:

Arranged in order of most soluble to least soluble in water:

$KCl > CH_{4} > C_{4} H_{9} OH > C_{3}H_{8}$

Explanation:

Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.

Non-polar molecules would be dissolved by non-polar solvents.

Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.
