5839516108	Equilibrium constant	Kc = products/reactants	0
5839516109	K>1	Forward reaction is favored	1
5839516110	Forward reaction	Reactants to Products	2
5839516111	Reverse reaction	Products to reactants	3
5839516112	K<1	Reverse reaction is favored	4
5839516113	K=1	neither reaction is favored	5
5839516114	Small equilibrium constant means...	reactants are favored	6
5839516115	Large equilibrium constant means...	products are favored	7
5839516116	Kc and Kp have what units?	they both have no units, but Kp is calculated using atm and Kc is calculated using molarity	8
5839516118	What equation connects Kp and Kc?	Kp = Kc(RT)deltaN [delta N= (c+d) - (a+b)]	9
5839516119	Solids and liquids are...	completely omitted from equilibrium expression	10
5839516120	Reaction Quotient	Q = products/reactants	11
5839516122	Difference between K and Q	Q uses initial quantities and K uses equilibrium quantities	12
5839516126	Q > K	reactions goes to the left (reactants)	13
5839516127	Q < K	reaction goes to the right (products)	14
5839516128	Q = K	reaction is at equilibrium	15
5839516134	Le Chateller's Principle	when a chemical system at equilibrium is disturbed, the system shifts in the direction that minimizes the disturbance	16
5839516135	Adding product...	shifts left	17
5839516136	Adding reactant...	shifts right	18
5839516137	Removing product...	shifts right	19
5839516138	Removing reactant...	shifts left	20
5839516139	Increasing volume (decreasing pressure)...	shifts toward the side with the more moles	21
5839516140	Decreasing volume (increasing pressure)...	shifts toward the side with the least amount of moles	22
5839516141	In 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
5839516142	In 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
5839516143	In 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
5839516144	In 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
5839516145	Adding a catalyst...	DOES NOT change the concentration	27
5839516146	Adding an inert (Noble) gas...	DOES NOT change the concentration	28
5839516147	If the reaction is reversed	invert Kc ; 1/Kc	29
