Exothermic reaction, an Uncommon card
In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release stored energy as heat.

Exothermic reaction quiz: 3 questions
Three questions on the Exothermic reaction card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Most of the ______ chemical reactions that are demonstrated in classrooms are exothermic and exergonic.
Answer
spectacular. Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic. From the Exothermic reaction article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Saurabh Tiwary. Saurabh Tiwary 51 · Exothermic reaction 47 · Tare weight 42 · Francesco Cigalini 39 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Sakichi Toyoda. Sakichi Toyoda 72,000 · Exothermic reaction 57,000 · Tare weight 33,000 · Francesco Cigalini 170 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- The term is often confused with exergonic reaction, which IUPAC defines as "... a reaction for which the overall standard Gibbs energy change ΔG⚬ is negative." A strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬.
- Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic.
- The opposite is an endothermic reaction, which usually takes up heat and is driven by an entropy increase in the system.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Exothermic reaction article was read about 57,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 47 and blocks with 22: each hit it takes is cut by 9 %.
How to get Exothermic reaction
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
