Meaning of subscript r

Postby Sierra Cheslick 2B » Mon Feb 18, 2019 3:28 pm

What does the subscript "r" mean when used in relation to either deltaH or deltaS? This is used in the solutions manual for 9.67 in the 6th edition.

I'm not sure but I think it just means reaction

The subscript r is an abbreviation of "reaction." Thus delta H "r" would imply the change in enthalpy of the reaction and delta S "r" would signify the entropy change of the reaction.

r signals that its for a reaction, but it doesn't really change anything so don't worry about it.
