When the system was at equilibrium, there was no net reaction. Now that the equilibrium is disturbed, there will be a net reaction in the direction of reactants or products (depends on the specifics of how the equilibrium was disturbed). The jargon for this net reaction is to say the equilibrium “shifted to the left” (or to the right).

2019年1月12日 · Yes, for some reason the reaction is out of equilibrium, otherwise there would be no net reaction (no "shift"). I'm confused with the terms "position of equilibrium" and "equilibrium shifting towards left/right". "Position of equilibrium" could be roughly equated with the set of all concentrations at equilibrium.

2016年3月2日 · For a reaction to be in equilibrium, the concentrations of reactants and products must be related by the equilibrium constant. $$ \ce{ A <=> B} $$ $$ K = \frac{[B]}{[A]} $$ When equilibrium constants are extremely large or small, then extremely large numbers of molecules are required to satisfy this equation.

2016年1月4日 · According to IUPAC: Quantities, Units and Symbols in Physical Chemistry, the arrows are used differently for composite mechanisms in chemical kinetics. In case of a simple mechanism that is composed of a forward and a reverse elementary reaction (i.e. reactions that occur at the molecular level in one step), it is conventional to write these in ...

2024年12月14日 · While studying equilibrium, I came across this question-CO(g) + 2H₂(g) ⇌ CH₃OH(g) Hydrogen gas is introduced into a 5-L flask at 327°C, containing 0.2 mol of CO(g) and a catalyst, until the pressure is 4.92 atm. At equilibrium, 0.1 mol of CH₃OH(g) is formed. If the value of Kp = β/(4.92)^2. What is the value of β?

2019年7月26日 · A chemical equilibrium can be established only if none of the products is allowed to escape out or separate out as a solid (precipitate) I understand that if one of the products is a gas and escapes out the reaction won't be able to proceed in the backward direction since that gas is no more a part of the system.

2020年4月2日 · Therefore, increasing their concentration pushes equilibrium to the other side of the reaction and vice versa. There is a big touch difference between $\ce{NaCl(aq)}$ and $\ce{NaCl(l)}$. The former serves for sea bathing/swimming, the latter would make from your body a piece of carbon within seconds. See e.g. Solubility equilibrium.

2019年9月5日 · Unfortunately for learners of chemistry, statements like "the equilibrium shifts to the right" are quite common jargon. What is meant by this, speaking in more accurate technical terms, is the following: A reaction had reached equilibrium (net reaction is zero), and then some change occurred so that it was no longer in equilibrium.

2014年8月3日 · Dynamic equilibrium is the state for a reversible reaction, in which the rate of both the forward and backward direction is equal and thus the overall change is zero. In this case, the ratio would equal one.

2019年3月11日 · A reaction is at equilibrium if reactants and products are both present, the forward and reverse rates are equal and the concentrations don't change over time. If this is the only reaction in a closed, isolated system, the entropy in the system is constant. Steady-state implies a system that is not at equilibrium (entropy increases).
