Demonstrates an equally simple proof to Weltin's that shows that equilibrium concentrations for a chemical reaction are always uniquely determined by the initial concentrations. Description; Principles used; Requirement of individual properties of P and R.Glaister...
A point worth emphasizing is that hydrostaticequilibriumis fulfilled with great accuracy in stellar atmosphere. 值得强调指出,在恒星大气中,流体静力平衡是非常精确地成立的. 辞典例句 An exogenous shock to exports will lower theequilibriumoutput of the economy. ...
a化学平衡是指在宏观条件一定的可逆反应中,化学反应正逆反应速率相等,反应物和生成物各组分浓度不再改变的状态。 The chemical equilibrium is refers in macroscopic condition certain reversible reaction, the chemical reaction back reaction speed is equal, the reactant and the resultant various components densit...
5. Which of the following statements best describes the condition(s) needed for a successful formation of a product in a chemical reaction? (A)The collision must involve a sufficient amount of energy, provided from the motion of the particles, to overcome the activation energy. ...
The disclosed invention relates to a process for conducting an equilibrium limited chemical reaction in a microchannel reactor. The process involves the use of active heat exchange and is suitable for conducting exothermic and endothermic reactions. The process is particularly suitable for synthesizing met...
