Standard Gibbs

[Justin Bui 2L]

Can someone give me a concise explanation of what standard means? Or when Delta G has that little degree sign following it. This also shows up in other formulas.

I'm pretty sure that standard refers to the standard state of the molecule (Ex: gas, liquid or solid). It is also at 273.15K and 1 atm pressure.

Standard just indicates that all reactants and products are in their standard state.

Standard state for a gas is 1 atm. Standard state for a solution is 1M at 1 atm. Standard state for an element is the most stable phase (solid, liquid, gas) at 1 atm and temperature of interest (25⁰C).

[Rishi Khettry 1L]

The sign indicates standard state which means it is taking place under standard conditions (aka 25 degrees Celsius and 1 atm)
