Why do some chemical reactions happen without any outside help?
In short: Understanding spontaneity is key to predicting how nature behaves. This video explains the thermodynamic rules that determine whether a process will occur on its own or require an external energy source.
Paul Andersen explores the distinction between spontaneous and non-spontaneous processes. A reaction is considered spontaneous when it is thermodynamically favored, meaning it can proceed without any input of energy from the outside environment.
The video outlines specific thermodynamic criteria for these occurrences: a process will be spontaneous if it results in a negative enthalpy change (releasing heat) and a positive entropy change (increasing disorder).
