Free energy

Postby Dina 2k » Thu Feb 06, 2020 8:54 pm

what is the relationship between standard free energy and free energy change?

i think it is deltaG = standard G + RTlnQ

Standard free energy is measured in a lab under standard conditions (usually is denoted with a degree symbol). Delta G can be measured in a situation that isn't in standard conditions like in a biological system.

I think the standard free energy conditions is the one measured in the lab and the regular free energy change occurs in real life systems

So would we need to know anything more than just the sources of error/ comparison between these?

Probably not, since we haven't learned that equation yet but the equation relating the two are delta G = delta G not + RTlnQ if that helps.

thank you!
