Chemistry R Constant Used To Calculate Free Energy

\n\n\n

\n

\n \n

The Universal Gas Constant (R) is a fundamental constant in physical chemistry used to relate pressure, volume, temperature, and the amount of gas. It is used in the Ideal Gas Law ($PV = nRT$) and thermodynamic calculations involving free energy.
