10 A: 300 °C, the equilibrium constant for the reaction 2J(g)=2K(g) + L(g) is x.What is the equilibrium constant for the following reaction at the same temperature? A$$ K ( g ) + V _ { 2 } L ( g ) \rightleftharpoons J ( g ) $$ A. $$ \frac { 1 } { \sqrt ...
Temperature is one of the most frequently used physical parameters, commonly measured but not exactly definable under conditions of non-equilibrium. The first part of this article is devoted to a general understanding of temperature and its measurability. In the second part we deal in detail with...
What three factors affect the heat transfer that is necessary to change an object's temperature? how does temperature affect the time it takes to reach thermal equilibrium? How is the heat capacity of a body related to the specific heat capacity of its substance?
Shortly after Einstein started a revolution in physics with his famous work on special relativity, a problem was proposed: consider a system A in thermodynamic equilibrium, and two inertial frames, I and I′. Frame I is at rest with respect to A and I′ is moving with speed w with ...
What is the temperature at a, b, c, d? Thermodynamics: Thermodynamics deals with the physics of heating objects. When the temperature of a system is increased, the atoms or molecules inside will oscillate randomly about a mean position. Thermo current will be there due to the random movement...
What is the equilibrium constant, K for the following reaction at 400 K? 2NOCl(g) iff 2NO(g) + Cl_2(g) Delta H = 77.2 kJ "mol"^(-1) and Delta S = 122 JK^(-1) "mol"^(-1) at 400 K View Solution ∘ View Solution ...

根据下文“better equilibrium control”可知,因为女性重心较低,所以平衡控制能力好。故选D。 (11)题详解: 考查名词词义辨析。句意:巴黎奥运会是第一届男女运动员人数相等的奥运会。A. performers表演者;B. athletes运动员;C. participants参与者;D. spectators观众。根据句中的“The Paris Olympics”可知,此处指...
example is the reaction between hydrogen and nitrogen to make ammonia. The reaction is so slow at room temperature that nothing happens. If you increase the temperature to speed the reaction up, however, the balance at equilibrium shifts back towards reactants, and very little ammonia is ...
Another kind of equilibrium that we learned in chemistry is thermal equilibrium. This is what happens when we hold a piece of metal in our hand for some time, for example. The heat from hand will transfer to the metal and will change its temperature. The metal will become warmer and warme...
