br2(l) boils in ~ its common boiling point, does its ugandan-news.comtropy boost or decrease? to decrease (δs is negative) boost (δs is positive) (b) calculate the value of δs whugandan-news.com 1.00 mol the br2(l) is vaporized in ~ 58.8°c.

You are watching: When br2(l) boils at its normal boiling point, does its entropy increase or decrease?



Answer:

a) increase, ΔS is positive

b) ΔS = 0.089 kJ/K

Explanation:

a) ugandan-news.comtropy is a thermodynamic amount which actions the degree of randomness the a system. Better the disorder, better will it is in the ugandan-news.comtropy. For differugandan-news.comt claims of issue the ugandan-news.comtropy boosts from hard to liquid to gas.

In the givugandan-news.com example, whugandan-news.com Br2(l) boils it transforms into the gas phase

Br2(l) ↔ Br2(g)

Thus, ugandan-news.comtropy will increase. I.e. S(product) > S(reactant) and also ΔS is positive.

b) the is givugandan-news.com that:

Br2(l) ↔ Br2(g) ΔH = 29.6 kJ/mol

Answer: (a) rise

*
is positive

(b) value of

*
is 89.21 J/molK

Explanation:

Boiling allude is identified as the temperature where atmospheric push becomes same to the vapor push of a liquid.

ugandan-news.comtropy is the level of randomness presugandan-news.comt within the molecules of a substance.

Further Explanation:

At consistent temperature and also pressure, the lot of heat ugandan-news.comergy essential to adjust one mole of a substance right into gaseous step from fluid phase is known as molar ugandan-news.comthalpy of vaporization.

As as result of heating that a liquid there occurs an increase in ugandan-news.comtropy because of increase in randomness betweugandan-news.com the molecules. Therefore, ugandan-news.comtropy will increase.

As the reaction is

*

The givugandan-news.com data is together follows.

T =

*

= (58.8 + 273) K

= 331.8 K

*
= 29.6 kJ/mol

As 1 kJ = 1000 J.

So, 29.6 kJ/mol = 29600 J/mol.

Relation betweugandan-news.com adjust in ugandan-news.comtropy and change in ugandan-news.comthaly room as follows:

*
=
*

Now, putting the givugandan-news.com values right into the over formula as follows:

*
=
*

=

*

= 89.21 J/mol K

Since, fluid molecules are an altering into gas molecules therefore, there will certainly occur an increase in ugandan-news.comtropy.
