Radioactive decay is a chemical process that will occur indefinitely. It will eventually reach such a low level of radioactivity that any change is not measurable, but theoretically speaking this "reaction" never stops. Other than that I can't think of any reactions that will go on for that long without some change in their environment. Equilibrium reactions will shift regardless of how long ago they reached equilibrium if they detect some change (change in temperature, concentration of reactants or products, change in pressure or volume of their reaction vessel), but I don't think that's the sort of "goes on for years" you were asking for.

What is another term for chemical change?
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
What tells the story of a chemical reaction?
The balanced chemical equation for a reaction tells the story of a chemical reaction by showing the reactants that are consumed and the products that are formed. It also provides information on the stoichiometry of the reaction, including the ratios of reactants and products involved.
Define chemical reaction and chemical equation?
A chemical reaction is a process that results in the transformation of chemical substances into new substances with different properties. A chemical equation represents this reaction using chemical formulas of the reactants and products, along with their respective coefficients to balance the equation.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What do you call substances that are made by a chemical reaction?
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
What goes under no chemical change in a chemical reaction?
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
Is there a chemical reaction when a firework goes off?
Yes.
What goes into a chemical reaction and undergoes change?
reactants
What is it called when a substance under goes a chemical change?
A chemical reaction occur.
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.
Is wood burning a chemical reaction or a physical reaction?
The burning of a wooden stick is a chemical process.
When does a chemical reaction go to completion?
A chemical reaction goes to completion when all the reactants have been fully converted into products, with no remaining reactants left.
In a chemical reaction the left side of the equation which tells you what goes into the reaction are called the?
Products. Products ----> Reactants.
How is chemistry used un firefighting?
When fire is created, it goes through a chemical reaction.
What are the chemicals that we end up with in a reaction?
Any chemical reaction creates a new substance.
In terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid.?
The chemical reaction goes faster if calcium carbonate is powdered.
