the step-by-step sequence of reactions by which the overall chemical change occurs reaction mechanism
species that appear in some steps but not in the net equation intermediate
reaction in whose reactants and products exist in a single phase homogeneous reaction
set of assumptions regarding collisions and reactions collision theory
the minimum energy required to transform the reactants into an activated complex activation energy
a transitional structure that results from an effective collision and that persists while old bonds are breaking and new bonds are forming activated complex
the change in the concentration of reactants per unit of time as the reaction proceeds reaction rate
the area of chemistry that is concerned with reaction rates and reaction mechanisms chemical kinetics
involve reactants in two different phases heterogeneous reaction
a substance that changes the rate of a chemical reaction without itself being permanently consumed catalyst
the action of a catalyst catalysis
a catalyst that is in the same phase as all the reactants and products in a reaction system homogeneous catalyst
a catalyst that is phase different from that of the reactants heterogeneous catalyst
the slowest-rate step for a chemical reaction rate-determining step

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.
