化学反応
化学反応
A balanced chemical equation provides the information of chemical formulas of the reactants and products involved in the chemical change. A ...
エンタルピーと反応熱
エンタルピーと反応熱
Combustion, commonly known as burning, is a reaction in which a substance reacts with an oxidizing agent, which in most cases is molecular oxygen, to ...
溶液形成のエネルギー論
溶液形成のエネルギー論
The formation of a solution is an example of a spontaneous process, which is a process that occurs under specified conditions without energy from some ...
エントロピーとソルベーション
エントロピーとソルベーション
The process of surrounding a solute with solvent is called solvation. It involves evenly distributing the solute within the solvent. The rule of thumb for ...
ギブス自由エネルギーと熱力学的好感度
ギブス自由エネルギーと熱力学的好感度
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or ...
化学および溶解度平衡
化学および溶解度平衡
The free energy change associated with dissolving a solute in a liter of solvent is called the free energy of a solution, ΔGsolution. The overall ...
レート法と反応順序
レート法と反応順序
The rate of a reaction is affected by the concentrations of reactants. Rate laws (differential rate laws) or rate equations are mathematical expressions ...
温度変化が反応速度に及ぼす影響
温度変化が反応速度に及ぼす影響
The Arrhenius equation, relates the activation energy and the rate constant, k, for many chemical reactions. In this equation, R is the ideal gas ...
マルチステップ反応
マルチステップ反応
Chemical reactions often occur in a stepwise fashion involving two or more distinct reactions taking place in a sequence. A balanced equation indicates ...
結合解離エネルギーと活性化エネルギー
結合解離エネルギーと活性化エネルギー
Bond energy is the energy required to break a bond homolytically. These values are usually expressed in units of kcal/mol or kJ/mol and are referred to as ...
エネルギー図、遷移状態、および中間体
エネルギー図、遷移状態、および中間体
Free-energy diagrams, or reaction coordinate diagrams, are graphs showing the energy changes that occur during a chemical reaction. The reaction ...
反応結果の予測
反応結果の予測
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, ...
