Which of these processes involve the weakening of the attraction between particles

Chemistry

AveGali [126]3 years ago
3 0

Answer : The correct option is (3) Evaporation.

Explanation :

Evaporation : It is a process in which the liquid particles are converted to gaseous particles. The inter-molecular forces of attraction between the liquid particles will be weakened. As a result the phase change occurs.

Freezing  : It is a process in which a phase changes from liquid state to solid state.

Condensation : It is a process in which a phase changes from gaseous state to liquid state.

Crystallization : It is a process in which a solute particles get separated from the solvent in the form of crystals ( in solid phase).

Whereas in freezing, condensation and crystallization we are moving from one phase having weaker inter-molecular forces of attraction to another phase having stronger inter-molecular forces of attraction. So, in these processes strengthening of attraction between the particles takes place.

Hence, the correct answer is Evaporation.

The freezing point of ethanol, CH3CH2OH, is -117.300 °C at 1 atmosphere. Kf(ethanol) = 1.99 °C/m
MAXImum [283]

Answer : The molecular weight of this compound is 891.10 g/mol

Explanation :  Given,

Mass of compound = 12.70 g

Mass of ethanol = 216.5 g

Formula used :  

\Delta T_f=i\times K_f\times m\\\\T_f^o-T_f=i\times T_f\times\frac{\text{Mass of compound}\times 1000}{\text{Molar mass of compound}\times \text{Mass of ethanol}}

where,

\Delta T_f = change in freezing point

T_f^o = temperature of pure ethanol = -117.300^oC

T_f = temperature of solution = -117.431^oC

K_f = freezing point constant of ethanol = 1.99^oC/m

i = van't hoff factor = 1   (for non-electrolyte)

m = molality

Now put all the given values in this formula, we get

(-117.300)-(-117.431)=1\times 1.99^oC/m\times \frac{12.70g\times 1000}{\text{Molar mass of compound}\times 216.5g}

\text{Molar mass of compound}=891.10g/mol

Therefore, the molecular weight of this compound is 891.10 g/mol
