Reversible reactions and closed systems
Reversible reactions and closed systems
Some reactions can go in both directions. A reversible reaction is shown with the symbol ⇌\rightleftharpoons⇌, for example NH4Cl(s)⇌NH3(g)+HCl(g)NH_4Cl(s) \rightleftharpoons NH_3(g) + HCl(g)NH4Cl(s)⇌NH3(g)+HCl(g), where the products can react to remake the original reactants.
