Equation 15 · Part 2 · The Statistical Mechanics of Irreversibility at Molecular Scale

Symbol Δ F

W=ΔFW=\Delta F
ΔF\Delta F

What this part means

Δ F is an input to the expression that computes the quantity on the left.

Its job in the formula

Δ F is an input to the expression that computes the quantity on the left.

The passage around this formula

At W=Δ\Delta F , the ratio equals one, so the forward distribution and the reflected reverse distribution cross. This provides both a geometric interpretation and an experimental route to free-energy differences.
