Question

the reaction of sodium with oxygen. a) endothermic and spontaneous. b) endothermic and non spontaneous. c) exothermic and non spontaneous. d) exothermic and spontaneous​

Answer 1

A spontaneous process is capable of proceeding in a given direction without needing to be driven by an outside source of energy.

The laws of thermodynamics govern the direction of a spontaneous process, ensuring that if a sufficiently large number of individual interactions are involved, then the direction will always be in the direction of increased entropy.

An endergonic reaction (also called a nonspontaneous reaction) is a chemical reaction in which the standard change in free energy is positive and energy is absorbed.

Endergonic processes can be pushed or pulled by coupling them to highly exergonic reactions.
