Which of these species would you expect to have the highest standard entropy (S°)? a. CH4(g)
b. C2H2(g)
c. C2H4(g)
d. C2H6(g)
e. C3H8(g)

e. C₃H₈(g)

Explanation:

Standard entropy is the absolute  entropy of a substance at 1 atm and 25°C.

For  different substances in the same phase, molecular complexity determines which ones have higher entropies.

Consider the gases CH₄, C₂H₂, C₂H₄, C₂H₆, C₃H₈. Propane (C₃H₈) has a more complex structure and hence more ways to execute molecular motions, which also increase its microstates. Therefore,  propane has the greatest standard entropy.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

there all right good
