# In the reaction B + K leftrightarrow L + H, if an additional B is added, what will be the result?

Sep 4, 2016

Since $B$ is a reactant; adding more of $B$ will result is the equilibrium shifting to the right side (products side) to minimize the amount of $B$ added.

#### Explanation:

Let us write the equilibrium equation again,

$B + K r i g h t \le f t h a r p \infty n s L + H$

According to Le Châtelier's principle, when a reactant is added to a system at equilibrium, the reaction will proceed in the direction to minimize the concentration (or pressure) of the reactant added.

The same explanation could be used if a product is added to a system at equilibrium.

Since $B$ is a reactant; adding more of $B$ will result is the equilibrium shifting to the right side (products side) to minimize the amount of $B$ added.
