Activation energy, an Uncommon card
In the Arrhenius model of reaction rates, activation energy is the minimum amount of energy that must be available to reactants for a chemical reaction to occur.

Power 103 (ATK + DEF): stronger than 55 % of WikiCards cards.
Activation energy quiz: 3 questions
Three questions on the Activation energy card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The activation energy of a ______ is measured in kilojoules per mole or kilocalories per mole.
Answer
reaction. The activation energy of a reaction is measured in kilojoules per mole or kilocalories per mole. From the Activation energy article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Symmetry. Symmetry 70 · Activation energy 64 · Cofferdam 59 · Ammonium acetate 53 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Cofferdam. Cofferdam 58,000 · Activation energy 44,000 · Ammonium acetate 30,000 · Symmetry 24,000 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 activation energy of a reaction is measured in kilojoules per mole or kilocalories per mole.
- Simplified: Activation energy is the minimum energy barrier that reactant molecules must overcome to transform into products.
- A reaction occurs only if enough molecules have kinetic energy equal to or greater than this barrier, which usually requires sufficiently high temperature.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Activation energy article was read about 44,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 64 and blocks with 39: each hit it takes is cut by 16 %.
How to get Activation energy
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.
