Favorable chemical reactions are those that release energy, produce a decrease in entropy, or result in the formation of more stable products. These reactions typically proceed in the direction of equilibrium and are thermodynamically spontaneous. Examples include combustion reactions and exothermic reactions.
Reaction D would result in decreased entropy, as the solid reactant (MgCl2) is breaking into ions in solution, which typically decreases entropy. The other reactions involve gases as reactants or products, which generally increase entropy due to higher degrees of freedom in gaseous states.
An example of a reaction that would result in decreased entropy is a dehydration reaction.

The meaning is more order.
Processes that result in a decrease in entropy and internal energy typically involve the transfer of energy out of a system, such as in exothermic reactions or phase transitions like freezing. In these cases, the system loses heat to its surroundings, leading to a more ordered state and lower entropy. Additionally, work done on the system, such as compression, can also decrease internal energy and entropy if it results in a more organized arrangement of particles. Overall, these processes favor stability and order at the expense of energy availability.

They could be used for making science test or other things, per example: Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.
