Walther Nernst

Walther Nernst was a German chemist known for his work in physical chemistry and thermodynamics. He developed the Nernst equation, which describes how the voltage of an electrochemical cell depends on the concentration of reactants and products. This equation is foundational in understanding chemical reactions and energy changes. Nernst also contributed to the third law of thermodynamics, which states that as temperature approaches absolute zero, the entropy of a perfect crystal approaches zero. His insights laid the groundwork for modern chemistry, linking macroscopic properties and molecular behavior in both chemical and physical processes.
