It gets transformed into other types of energy, never destroyed nor created.
they decay over time
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
Yes, of course... Work is power which is energy absorption or use over time. No energy, no work regardless of how much time is allowed.
Activation energy is required to initiate a reaction by breaking bonds in the substrate molecules. This energy is necessary to overcome the energy barrier and trigger the reaction to proceed. Once the reaction is initiated, the catalytic action of the enzyme can lower the activation energy required for subsequent steps in the reaction.

Copper, over the course of time, is gradually oxidized when exposed to air. It takes quite awhile for this reaction to occur naturally; however, the reaction is expedited with heat. The result is Copper oxide.
Powdered: increases surface area the reaction happens over, thereby increasing the rate of reaction Heat: Provides energy for the reaction. Particles move faster, therefore collide more frequently. also, more particles have sufficient energy to react when they collide. This also increases rate.

Well, I believe that over the course of a few weeks our Moon just changes phases, besides that I don't think anything else happens to it...

The products are favored over the reactants if the reaction is exothermic, releasing energy. Conversely, the reactants are favored over the products if the reaction is endothermic, requiring energy input.
In general, and depending on the order of the reaction, the rate will decrease as the reaction progresses.

Enzymes lower the activation energy of a reaction, acting as a catalyst and speed up the reaction. Plus they never get used up, only over and over again.

Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
