Detailed Breakdown: Equilibrium
The Dynamic Nature of Equilibrium: In a closed system, reversible reactions reach a state where the forward and reverse rates are equal. Macroscopically, things look static, but microscopically, particles are constantly transforming and returning, maintaining constant concentrations.
Le Chatelier’s Principle: Management of Yield: If a stress (change in $T, P, \text{ or } C$) is applied to a system at equilibrium, the system will shift its position to oppose the stress. Industrially, we use this to 'force' reactions toward products by removing them as they form.
The Equilibrium Constant ($K_c$): $K_c$ is a mathematical ratio of product and reactant concentrations ($[P]/[R]$). If $K_c \gg 1$, the reaction goes almost to completion. If $K_c \ll 1$, the reaction hardly proceeds. Only temp changes can change the value of $K_c$.
