The Concept of Equilibrium

The Concept of Equilibrium. Chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate. The Concept of Equilibrium. As a system approaches equilibrium, both the forward and reverse reactions are occurring.

What is the equilibrium chemical equation?

Calculate the pH of a solution that is 0.150 M in Benzoic acid (HC 7 H 5 O 2 ) and 0.050 M in potassium benzoate (KC 7 H 5 O 2 ). The pK a of benzoic acid is 4.20). This is a buffer solution since it contains a weak acid and its conjugate base (a salt of the acid).
