Spontaneous chemical reactions proceed until they hit equilibrium. Once the reaction hits equilibrium, it stops until the product or reactant concentration changes. The reaction will then start again until the equilibrium concentrations of reactants and products are restored. If the statement isn’t accurate then tell me why that is the case.
