🤓 Based on our data, we think this question is relevant for Professor All professors' class at GS.
We are asked which of the given statements suggest an increase in entropy (i.e. +ΔS).
The statements given describe the spontaneity of the reaction.
Entropy is the disorder or chaos associated with a system’s inability to convert thermal energy into mechanical work.
The 2nd Law of Thermodynamics (i.e. relating to entropy) states systems (chemical reactions) spontaneously move to a state of disorder, hence:
Sfinal > Sinitial = +ΔS
For nonspontaneous reactions:
Sfinal < Sinitial = -ΔS
For which of the following processes does the entropy of the system increase?
(a) the ripening of a banana,
(b) dissolution of sugar in a cup of hot coffee,
(c) the reaction of nitrogen atoms to form N2 molecules at 25 and 1 atm,
(e) formation of CH4 and O2 molecules from CO2 and H2O at room temperature and 1 atm of pressure?
