5839516108Equilibrium constantKc = products/reactants0
5839516109K>1Forward reaction is favored1
5839516110Forward reactionReactants to Products2
5839516111Reverse reactionProducts to reactants3
5839516112K<1Reverse reaction is favored4
5839516113K=1neither reaction is favored5
5839516114Small equilibrium constant means...reactants are favored6
5839516115Large equilibrium constant means...products are favored7
5839516116Kc and Kp have what units?they both have no units, but Kp is calculated using atm and Kc is calculated using molarity8
5839516118What equation connects Kp and Kc?Kp = Kc(RT)deltaN [delta N= (c+d) - (a+b)]9
5839516119Solids and liquids are...completely omitted from equilibrium expression10
5839516120Reaction QuotientQ = products/reactants11
5839516122Difference between K and QQ uses initial quantities and K uses equilibrium quantities12
5839516126Q > Kreactions goes to the left (reactants)13
5839516127Q < Kreaction goes to the right (products)14
5839516128Q = Kreaction is at equilibrium15
5839516134Le Chateller's Principlewhen a chemical system at equilibrium is disturbed, the system shifts in the direction that minimizes the disturbance16
5839516135Adding product...shifts left17
5839516136Adding reactant...shifts right18
5839516137Removing product...shifts right19
5839516138Removing reactant...shifts left20
5839516139Increasing volume (decreasing pressure)...shifts toward the side with the more moles21
5839516140Decreasing volume (increasing pressure)...shifts toward the side with the least amount of moles22
5839516141In an endothermic reaction, increasing temperature means...shifts right The value of K increases because the concentration of the products increase and the concentration of the reactants decrease.23
5839516142In an endothermic reaction, decreasing temperature means...shifts left The value of K decreases because the concentration of the products decrease and the concentration of the reactants increase.24
5839516143In an exothermic reaction, increasing temperature means...shifts left The value of K decreases because concentration of the products decrease and the concentration of the reactants increase.25
5839516144In a exothermic reaction, decreasing temperature means...shifts right The value of K increases because the concentration of the products increase and the concentration of the reactants decrease.26
5839516145Adding a catalyst...DOES NOT change the concentration27
5839516146Adding an inert (Noble) gas...DOES NOT change the concentration28
5839516147If the reaction is reversedinvert Kc ; 1/Kc29
