Your title is the reason - "and the origin of life"
on a molecular level reactions occur that either give off energy or need energy to complete.
in a balanced system one reaction could give off energy that is used by another reaction to fuel it's completion.
the earth is not a balanced system however, as it receives energy from the sun and from impacts of meteors and similar bodies (one theory is that the moon is a remnant of a major collision).
with energy available there is no inherent problem for abiogenesis from the second law of thermodynamics.
