# Problem: Do the equilibrium concentrations of the reactants and products depend on their initial concentrations?

###### FREE Expert Solution

We’re asked to determine if the equilibrium concentrations of the reactants and products depend on their initial concentrations.

Recall that a reaction is at equilibrium when the rate of the forward reaction (favors products) is equal to the rate of the reverse reaction (favors reactants).

This means that:

• At equilibrium, there is no observable change in the concentration of both the products and reactants
• In other words, the ratio that expresses the relationship between the amounts of products and reactants present at equilibrium is constant; known as the equilibrium constant, K.  The expression for the equilibrium constant, K is:

$\overline{){\mathbf{K}}{\mathbf{=}}\frac{\mathbf{products}}{\mathbf{reactants}}}$

• Using an equilibrium constant, K, we can use an ICE chart to determine the equilibrium concentrations of species.
