Abstract
The equilibria of a gaseous mixture of nitrogen dioxide and nitrogen tetroxide is studied by measuring the velocity of a sound wave propagated through the gas. The degree of dissociation and the equilibrium constant are determined as functions of temperature from 0 to 50°C, and pressure from 0 to 1 atm. At 30°C, is found to be 0.214 atm. The heat of reaction is determined to be 14.59 kcal mol−1 for the second‐law value, and 13.65 kcal mol−1 for the third‐law value.
