The statement that leads to the highest entropy gain in the surroundings is An exothermic reaction in a cold environment. The correct option is B.
What is entropy?
Entropy in a closed system is the energy that is present in the environment, but it is unuseful for doing any work. Entropy is denoted by the letter S.
Exothermic reactions are those reactions in which the heat is released into the system when reactions occur. The reactant energy is greater than the product's energy because it has the potential energy which is released in the system.
Entropy will be gained in the cold system because entropy always increases in a system and never decreases, in the cold system the heat is produced and added in the form of entropy.
Thus, the correct option is B. An exothermic reaction in a cold environment.
