- What is chemical equilibrium?
👉chemical equilibrium refers to a state in a chemical reaction where the rates of the forward and reverse reactions are equal. At this point, the concentrations of reactants and products remain constant over time. It’s a dynamic balance where reactants continue to form products, and products continue to form reactants, but there’s no net change in the overall composition of the system.
In mathematical terms, for a generic chemical reaction:
[aA + bB
ightleftharpoons cC + dD]
The equilibrium constant, (K_{\text{eq}}), is defined as:
[K_{\text{eq}} = \frac{{[C]^c [D]d}}{{[A]a [B]^b}}]
👉Where:
([A]), ([B]), ([C]), and ([D]) represent the molar concentrations of species A, B, C, and D, respectively.
(a), (b), (c), and (d) are the coefficients from the balanced chemical equation.
When (K_{\text{eq}}) is large, it indicates that the equilibrium lies toward the products. Conversely, when (K_{\text{eq}}) is small, the equilibrium favors the reactants.
👉Factors affecting chemical equilibrium include temperature, pressure, and concentration. Le Chatelier’s principle states that if an external change (such as altering concentration or temperature) is applied to a system at equilibrium, the system will adjust to counteract that change and restore equilibrium.
👉Remember, chemical equilibrium is a fascinating concept that plays a crucial role in understanding chemical reactions! 🧪🔬
