Why is Delta G equal to 0 at equilibrium?

A spontaneous reaction has a negative delta G and a large K value. A non-spontaneous reaction has a positive delta G and a small K value. When delta G is equal to zero and K is around one, the reaction is at equilibrium.

What is the formula of entropy?

In statistical mechanics, Boltzmann's equation is a probability equation relating the entropy S of an ideal gas to the quantity W, the number of real microstates corresponding to the gas' macrostate: (1) where kB is the Boltzmann constant (also written as simply k) and equal to 1.38065 × 1023 J/K.
