Nonspontaneous Reaction

Definition

A nonspontaneous reaction is a chemical reaction that does not occur naturally without the input of energy.

Analogy

Think of a nonspontaneous reaction like pushing a boulder up a hill. It won't happen on its own; you need to put in effort (energy) to make it happen.

Related terms

Endothermic Reaction: This is a type of nonspontaneous reaction where heat is absorbed from the surroundings.

Activation Energy: The minimum amount of energy required for a chemical reaction to proceed, similar to the initial push needed to move the boulder uphill.

Endergonic Reaction: A type of nonspontaneous reaction that absorbs energy in the form of work.
