Sr. # Questions Answers Choice
1 Le Chatelier's Principle applies to. Irreversibel reactions Static equilibrium Dynamic equilibrium Precipitation reactions
2 Position of equilibrium is affected by Temperature Catalyst Inert gas Surface area
3 Q   <  K implies. Reaction proceeds forward quilibrium is established System stops Reaction fhifts in reverse
4 A large K value indicates. Prodcuts are favored Reactants are favored No reaction Slow reaction
5 Reaction quotient Q is calculated using Initial conceration  Equlibrium concentrations Temperature Catalyst
6 If Q > K, the reaction Shift left Moves forward At equilirbium Stops
7 If Q=K , then Reaction is irrversible System is at equilibium Forward reaction dominates Reverse reaction dominates
8 Kp = Kc(RT) is used to related. Kp and Kc Temperatur eand pressure Energy and volume Gibbs free energy
