A. Decomposing water requires a high activation energy.
Explanation:
In decomposing water to release hydrogen gas to make fuel cells, the process requires a very high activation energy.
2H₂O ⇆ 2H₂ + O₂
This is the overall reaction. O-H must be broken to release free hydrogen to produce hydrogen gas.
The O-H bond is a very strong force of attraction that requires a high activation energy to overcome.
- The activation energy is the energy barrier that must be overcome before a reaction takes place.
- The sun is a renewable source of energy.
- Water decomposition produces useful oxygen gas needed by all life for cellular respiration.

Explanation:
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
When interaction between the solute and solvent are weak then solution will evaporate readily into the atmosphere. Therefore, it means vapor pressure increases with particularly weak solute-solvent interactions.
On the other hand, when interactions between the solute and solvent of a strong enough in a solution then vapors are not formed easily. This also means that vapor pressure decreases with particularly strong solute-solvent interactions.
