In order to know and understand what is Delta G, we must first understand the concept of spontaneity.
A reaction is consider spontaneous when it can react with another element on it’s own, without the help from a catalyst.
Delta G is the symbol for spontaneity, and there are two factors which can affect it, and .
Enthalpy – the heat content of a system at constant pressure.
Entropy – the amount of disorder in the system.
Below is a table to summarize it up!
When delta G > 0 – It’s a non-spontaneous reaction.
When delta G < 0 – It’s a spontaneous reaction.
When delta G = 0 – It’s at equilibrium.
