Catalyst Increases rate of a chemical reaction without being consumed by the reaction
Enzyme A biological(protein) catalyst
Chemical Equilibrium State in which the rate of the forward reaction is equal to the rate of the reverse reaction, no change in concentration of products or reactants
Reversible Reaction A reaction that can occur in both the forward and reverse directions
