functions like DH, DS, and DG are always done from the FINAL state minus INITIAL state. Does that help?

anonymous · Answer

no, not at all.... sorry. cant you just tell me? lol @JFraser

jfraser · Answer

well it can't be reactant - reactant, or product - product, so it must be either:

reactant - product

or 

product - reactant

Which of those options is the same as "final" - "initial"

anonymous · Answer
