reactions/equlibrium

Chem

QuestionAnswer
reaction rate the change in concentration of a reactant or product per unit time, expressed as mol/(ls)
Collision theory atoms, ions, and molecules must collide with each other in order to react.
activated complex/transition state an intermediate particle made up of the joined reactants
activation energy minimum amount of energy that colliding particles must have in order to form an activated complex
catalyst/enzyme a substance that increases the rate of a chemical reaction without itself being consumed in the reaction
inhibitor a substance that slows down, or inhibits, reaction rates.
rate law the equation that expresses the mathematical relationship between the rate of a chemical reaction and the concentration of reactants
specific rate constant numerical value that relates reaction rate and concentration of reactants at a given temp.
reaction order the reaction order for a reactant defines how the rate is affected by the concentration of that reaction.
complex reaction a certain series of steps mus occur with correct fit and in an exact sequence in order to yield trhe reaction products
reaction mechanism the SERIES OF STEPS that must occur with correct fit and in an exact sequence in order to yield trhe reaction products
intermediate an atom,ion or molecule prduced in one step of a reaction adn consumed in a later step
rate-determining step determines how fast the reaction forms products, no matter how fast the other steps are
chemical kinetics the study of the sped at which chemical and physical processes take place
rate law a mathematical expression showing how a change in the concentration affects the rate of the reaction
reversible reation one that can occur in both the FORWARD and the REVERSE directions
chemical equlibrium a state in which the forward an dreverse reactions balance each otehr because they take place at equal rates
law of chemical equlibrium at a given temp, a chem system may reach a state in which a particular ration of reactant and product concentrations has a constant value
equilibrium constant the numerical value of the ration product concentrations to reactant concentrations, with each concentration raised to the power corresponding to its coefficient in the balanced equation

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.
