Write the chemical equilibria and the equilibrium expressions (reaction quotients) for the following equilibrium constants:
In chemical reactions, substances may interact and form products. Some reactions go to completion, while others reach a state of equilibrium, where the concentrations of reactants and products remain relatively constant over time. To describe these equilibrium states quantitatively, chemists use equilibrium constants, denoted as K, to express the ratio of product concentrations to reactant concentrations.
In this context, we will conside chemical equilibria and its equilibrium expressions, sometimes referred to as reaction quotients (Q). These expressions help us understand the position of equilibrium and how changing conditions might affect it.
