Thermochemistry

TermDefinition
Entropy disorder of the universe
Free Energy Spontaneity of a reaction
Enthalpy Heat
Exothermic heat goes from system to surroundings
Exothermic (sign) deltaH is negative
Endothermic heat goes from surroundings to system
Endothermic (sign) deltaH is positive
Hess's Law deltaH is the same if a reaction occurs in one step or a series of steps
Standard Enthalpy of Formation (equation) deltaH of reaction = sum of (moles of products x deltaH of formation of products) - sum of (moles of reactants x deltaH of formation of reactants)
Spontaneous (sign) deltaG is negative
Not Spontaneous (sign) deltaG is positive
Increasing Entropy (sign) deltaS is positive
Decreasing Entropy (sign) deltaS is negative
Spontaneity Equation deltaG = deltaH - TdeltaS
Calorimeter Equation q = s x m x deltaT

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
