Thermodynamics
and
is the
study of different forms of energy and their interconversion
flow of energy .
Thermodynamics helps in :
→
predicting feasibility of a reaction ie whether certain reaction,
.
is possible under
given conditions of temperature and pressure or not .
→
predicting extent of chemical reaction
the .
→
predicting the force that drives chemical (reaction ) process .
# SOME IMPORTANT TERMINOLOGIES : -
system , surroundings and Boundry
system -
Spe tic part of universe that is studied by us for study of energy
changes .
Surroundings Everything .

Boundary -
something that separate system from
surroundings .
