delta G knot

[Samantha Chung 4I]

What is the difference between delta G knot and delta G?

[michelle]

Like the concept in enthalpy. Delta G knot is the change in G under standard conditions (1 atm or 1 M). Delta G can be the change of free energy of the whole process(reaction).

[Xinyi Zeng 4C]

Just to add on, delta G (without knot) is calculated from delta H - T * delta S, while delta G knot is calculated from delta H knot - T * delta S knot. You can use delta G's equation to predict the effect of temperature and feasibility of a reaction, sometimes by just knowing the signs of delta H and delta S for any reaction, not under standard conditions

delta G knot indicates standard conditions, while regular delta G is the change in free energy under other conditions

g knot is the g value under standard conditions
