Answer: If 
for a reaction equals zero, the reaction is at equilibrium.
Explanation:
When a thermodynamic closed system tends to do the maximum amount of non-expansion work then the energy used to do this work is called Gibb's free energy.
The expression for can be written as follows.
where,
= enthalpy change
T = temperature
= entropy change
This means that is the difference between heat released in a process and the amount of heat released in a reversible manner for the same process. So, when the value of of comes out to be equal to zero then it means no heat is released or absorbed.
Hence, the reaction is stable or at equilibrium.
Thus, we can conclude that the value of = 0 then it means that the reaction is at equilibrium.

Scientists are able to detect an El Niño<span> event and its effects on the climate through a variety of technological and natural sciences. One of these natural sciences is dendrochronology, or the study of tree rings. Dendrochronologists study the rings of a tree in order to understand climatic conditions during specific time periods. Thin rings often indicate drier seasons while fatter rings indicate rainy seasons. Depending on where the tree is, scientists can see past El </span>Niño<span> events in trees that exhibit signs of much rainier or drier seasons that normal.</span>
