    Understanding Entropy: Molar Entropy of Helium vs Argon

    Thanks for the replies. =) Yeah, sorry about that. Helium's S is higher than Argon's. Similarly, Fluorine's S is lower than Chlorine's. And S of Methane < Ethane < Propane Why is that? This kind of suggests that size plays a role in entropy. Probably because there are more number of...

    Understanding Entropy: Molar Entropy of Helium vs Argon

    concept of "entropy." Hey, I am new to this concept of "entropy." And my book talks about it in terms of "the ways you can arrange something, more arrangements = more entropy." So, why is the molar entropy of Helium gas higher than that of Argon gas? There are the same number of particles...

    AS Chemistry Help: Enthalpy Change in Chain Alkanes

    Hi, this question is really bugging me. Thanks in advance. Homework Statement The difference between the enthalpy change of combustion if sucessive chain alkanes is around -650 kJ/mol Homework Equations Why does the value of enthalpy change of the sections of the chains have a...
