Question

Addition of $CCl_{4}$ to water is spontaneous or not.

Answer 1

Both water and $CCl_4$ are immiscible liquids, both do not mix to form a solution but they exist in contact with each other as separate layers. Once $CCl_4$ and water is mixed, $CCl_4$ would be the bottom layer and water sits on the top because of their difference in densities.

The density of $CCl_4$ = 1.4 g/mL

Density of water = 1.0 g/mL

Water is a polar and $CCl_4$ is non-polar, if both are mixed the ΔH value will be positive and ΔS is negative so that ΔG will be positive resulting in non-spontaneous reaction. So the dissolution does not readily occur.

Answer 2

Explanation:

Both water and CCl_4CCl

are immiscible liquids, both do not mix to form a solution but they exist in contact with each other as separate layers. Once CCl_4CCl

and water is mixed, CCl_4CCl

would be the bottom layer and water sits on the top because of their difference in densities.

The density of CCl_4CCl

= 1.4 g/mL

Density of water = 1.0 g/mL

Water is a polar and CCl_4CCl

is non-polar, if both are mixed the ΔH value will be positive and ΔS is negative so that ΔG will be positive resulting in non-spontaneous reac
