WebTools Nitrogen triiodide is an inorganic compound with the formula N I 3. It is an extremely sensitive contact explosive: small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; … In thermodynamics, the enthalpy of mixing (also heat of mixing and excess enthalpy) is the enthalpy liberated or absorbed from a substance upon mixing. When a substance or compound is combined with any other substance or compound, the enthalpy of mixing is the consequence of the new interactions … See more For a liquid, enthalpy of mixing can be defined as follows $${\displaystyle H_{(mixture)}=\Delta H_{mix}+\sum x_{i}H_{i}}$$ Where: • H(mixture) … See more An ideal mixture is any in which the arithmetic mean (with respect to mole fraction) of the two pure substances is the same as that of the final mixture. Among other important thermodynamic simplifications, this means that enthalpy of mixing is zero: See more Intermolecular forces are the main constituent of changes in the enthalpy of a mixture. Stronger attractive forces between the mixed … See more Enthalpy of mixing is often calculated experimentally using calorimetry methods. A bomb calorimeter is created to be an isolated system. With an insulated frame and a reaction … See more The excess Gibbs free energy of mixing can be related to the enthalpy of mixing by the ușe of the Gibbs-Helmholtz equation: $${\displaystyle \left({\frac {\partial (\Delta G^{E}/T)}{\partial T}}\right)_{p}=-{\frac {\Delta H^{E}}{T^{2}}}=-{\frac {\Delta H_{mix}}{T^{2}}}}$$ See more The heat of mixing for binary mixtures to form ternary one can be expressed as a function of mixing ratios of binary mixtures: See more • Apparent molar property • Enthalpy • Enthalpy change of solution • Excess molar quantity • Entropy of mixing See more
