Under what conditions can a non-spontaneous reaction be made spontaneous?

A non-spontaneous reaction can be made spontaneous if it is inside a controlled environment, ,This is what happens in nuclear power plants that create atomic fusion and fission in chambers that are controlled to control different particles to create nuclear active rays. These rays can be classified as alpha, beta, and gamma rays and are crucial for producing several forms of energy and proving different theories in chemistry and physics.

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
