Introduction:

Chemical Equilibrium

Equilibrium is defined as the balance between the forward and reverse rates of a reaction.

The formula for the Equilibrium Constant, is:

K_eq = [product] / [reactant][reactant]

The reaction in this lab is Fe³⁺ + SCN^- <--> FeSCN²⁺

The K_eq = [FeSCN²⁺] / [SCN^-][Fe³⁺]

In this lab, the concentrations of reactants will be known, and the product concentrations will be determined by using the spectrophotometer.
