MCAT Equilibrium

Chemistry Equilibrium

QuestionAnswer
Can equilibium constant (K eq) ever be negative? no
K(eq) < 1 means... reaction favors the reactants
K(eq) > 1 means... reaction favors the products
lowering temp favors... exothermic reactions
raising temp favors... endothermic reactions
Q > K(eq) means... the reacton procedes in the reverse
Q < K(eq) means... the reaction procedes forward
Exothermic reactions are located.... and ∆H is... on the product side; negative
Endothermic reactions are located... and ∆H is ... on the reactants side; positive
Adding a catalyst to a reaction that is already at equilibrium will have what kind of effect... adding a ( ) increases the rate of both the forward and reverse reactions equally, hoewever the equilibrium amounts will not change
In a reaction at equlibrium, if the volume is reduced, therefore increasing the pressure, a net reaction occurs favoring... the side with the smaller total number of moles
In a reaction at equlibrium, if the volume is expanded, therefore decreasing the pressure, the net reaction occurs favoring... the side with the greater total number of moles
What will happen to a reaction's equilibrium contsant K(eq) if the temp changes? The value of K(eq) is constant at a given temp therefore if the temp changes so does the K(eq)

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

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

If you've accidentally put the card in the wrong box, just tap 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.
