QuestionAnswer
rxn rate for forward rxn decrease in reactants/time = increase products/time
aA+bB--->cC+dD rxn rate = -1/a[A}/t= -1/b[B]/t= 1/c[C]/t= 1/d[D]/t
rate law for forward rxn states rate is proportional to conc of reactants
rate law formula rate=k [A]* [B]*
whats the order of a rxn x+y
solve rate law keep 1 trial constant then divide and solve for exponent
minimum energy 4 reactants to form products activation energy
has greater energy than either reactants /products transition energy= breaking old bonds and new bonds forming
________ the potential energy for products is less than the reactants exothermic (negative heat rxn)
temperature changed Ea, true / false false
temp effect on Ea increases the chances of molecules having energies higher than Ea colliding
________ lowers the activation energy Catalyst/ enzyme
reversible rxn eqn raised to its stoich coefficients =[C]^c*[D]^d/[A]^a*[B]^b products*/reactants*
le chatelier stress applied the system tends to change so as to relieve the stress
increasing Pressure _____ volume and favors ______ moles decrease; less
if keq equilib constant is > 1 forms alot of products
if Keq < 1 forms alot of reactants
Keq=1 equal products and reactants

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.
