The reaction H2(g)+F2(g)?2HF(g) is spontaneous at all temperatures. A classmate calculates the entropy change for this reaction
Pachacha [2.7K]

Answer:

The correct answer is there is a mistake in the calculation. The second law of thermodynamics state that in any spontaneous process there is an increase in the entropy of the universe.

Explanation:

According to the second law a reaction will occur in a system spontaneously if the total entropy of both system and surrounding increases during the reaction.That means in case of spontaneous reaction entropy change is always positive.

     But according to the question the reaction H2+F2=2HF is spontaneous in all temperature.So according to the second law of thermodynamics i can say that my classmate made a mistake in calculation that"s why his result for entropy change comes negative.

Sergio [31]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct place to click on any of the  double peak showing between  2500 and 3000cm^{-1} on the uploaded question

Explanation:

The group which is being highlighted is an Aldehyde  functional group denoted by this structure (=C-H)

This groups stretch on the infrared spectrometer gives two medium intensities peaks

Its stretch comes at  2820 - 2850 cm^{-1}  peak 1

and at  2720 - 2750 cm^{-1}  peak 2

So the correct click would be on any of the two peaks between 2500 - 3000 cm^{-1}  region
