- 1A + B <--> C + Dreversible reaction
- 2------------> <-------Reaction is product favored
- 3----> <-------------Reaction is reactant favored
- 4A + B --> C + DForward reaction
- 5C + D ---> A + BReverse reaction
- 6Keq aA + bB <--> cC + dDKeq =
[D]^d [C]^c /
[A]^a [B]^b - 7Keq >> 1reaction is product favored
- 8Keq << 1Reaction reactant favored
- 9Keq about equal to 1no direction is favored
- 10Reaction multiplied by a factor, K is...raised to the same factor
- 11Reaction is reversedK(reverse) = 1/K(forward) = 1/Keq
- 12When adding reactions together, their Keqs are...Multiplied together
- 13When writing equilibrium expressions, do NOT include...solids and pure liquids because they are considered condensed phases, therefore their concentration does not change
- 14Conversion of Kc to KpKc = Kp (1/RT) ^change in moles of gas
- 15Kp and Kc have units of...No units because each concentration and pressure is divided by their standard unit/state
- 16Mixed equilibrium constants have....units!
- 17R. I. C. EReaction. Initial (concentration/pressure). Change. Equilibrium
- 18If Q = K, reaction is....at equilibrium
- 19If Q < K....reactants are favored; reaction proceeds in the reverse direction
- 20If Q > K....products are favored; the reaction proceeds in the forward direction
- 21Le Châtelier's Principlewhen stress is applied on a system, the system will offset that stress in a specific fashion
- 22If more of a reactant is added to a reaction....the reaction will shift in the forward direction
- 23If more of a product is added to a reaction....The reaction will shift in the reverse direction...
- 24Solids and pure liquids added will...produce no change
- 25Catalysts added to a reaction will....produce no change
- 26If some of a reactant is removed from the reaction...the reaction will shift in the reverse direction
- 27If some of a product is removed from the reaction...the reaction will shift in the forward direction
- 28If the container the reaction takes place in expands, the reaction will....shift in the direction with the larger number of gas particles
- 29If the container the reaction takes place in compresses, the reaction will...shift in the direction with the smaller number of gas particles
- 30If heat is added to the reactionthe reaction will shift away from the heat (ie heat added to an endothermic reaction will drive it right; heat added to an exothermic reaction will drive it left)
- 31If a reaction is cooledthe reaction will shift toward the heat (ie heat removed from an endothermic reaction will drive it left; heat removed from an exothermic reaction will drive it right)
