  • Front
  • Back
a type of catalyst that slows down the reaction rate of a chemical reaction or prevents a reaction from happening
inhibitor
the state in which forward and reverse reactions balance each other because they occur at equal rates
chemical equilibrium
describes the ratio of product concentrations to reactant concentrations, with each raised to the power corresponding to its coefficient in the balanced equation
equilibrium constant
The change in concentration of a reactant or product per unit time, generally calculated and expressed in moles per liter per second.
reaction rate
A numerical value that relates reaction rate and concentration of reactant at a specific temperature.
specific rate constant
A short-lived, unstable arrangement of atoms that may break apart and re-form the reactants or may form products; also sometimes referred to as the transition state.
activated complex
The complete sequence of elementary steps that make up a complex reaction.
reaction mechanism
The minimum amount of energy required by reacting particles in order to form the activated complex and lead to a reaction.
activation energy
Can take place in both forward and reverse; leads to an equilibrium state where the forward and reverse reactions occur at equal rates and the concentrations remain constant.
reversible reaction
A substance that increases the rate of a chemical reaction by lowering activation energies but is not itself consumed in the reaction.
catalyst
