A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from a reversible process in thermodynamics. Weak acids and bases undergo reversible reactions. For example, carbonic acid: H 2 CO 3 (l) + H 2 O (l) ⇌ HCO 3 − (aq) + H 3 O + (aq).
File:Biochem reaction arrow Y XXXX Z med.svg. Y is a word indicating the chemical direction of the arrow, either "forward", "reverse", or "reversible". XXXX is a list of four characters indicating whether each side has an arrow or not. Each X is replaced with "Y" or "N" to indicate the presence or absence of a side arrow.

For example, adding more S (to the chemical reaction above) from the outside will cause an excess of products, and the system will try to counteract this by increasing the reverse reaction and pushing the equilibrium point backward (though the equilibrium constant will stay the same).

In 1884, Jacobus van 't Hoff proposed the Van 't Hoff equation describing the temperature dependence of the equilibrium constant for a reversible reaction: = where ΔU is the change in internal energy, K is the equilibrium constant of the reaction, R is the universal gas constant, and T is thermodynamic temperature.
In electrochemistry, the Randles–Ševčík equation describes the effect of scan rate on the peak current (i p) for a cyclic voltammetry experiment. For simple redox events where the reaction is electrochemically reversible, and the products and reactants are both soluble, such as the ferrocene/ferrocenium couple, i p depends not only on the concentration and diffusional properties of the ...
For an ideal reversible (Nernstian) reaction the theoretical peak separation (E PA - E PC) is 57 mV [1]. In electrochemistry , cyclic voltammetry ( CV ) is a type of voltammetric measurement where the potential of the working electrode is ramped linearly versus time.
