Sr. # Questions Answers Choice
1 Reaction quotient Q is calculated using Initial conceration  Equlibrium concentrations Temperature Catalyst
2 If Q > K, the reaction Shift left Moves forward At equilirbium Stops
3 If Q=K , then Reaction is irrversible System is at equilibium Forward reaction dominates Reverse reaction dominates
4 Kp = Kc(RT) is used to related. Kp and Kc Temperatur eand pressure Energy and volume Gibbs free energy
5 Kp is used for. Solid state reactions Gaseous reactions Aqueous reactions Liquid reactions
6 If Kc> 1, the reaction. Favors products Favors reactants Is at equilirbium Does not occur
7 Equilibrium constant depends on Pressure Temperature Volume Concentration
8 Kc is expressed in terms of. Pressure Mole fraction Concentration Volume
9 Law of mass action applies to Closed systems only Open systems Irreversibel systems Combustion reactions
10 Active mass means Moles Volume Mass Molar concentration
11 According to law of mass action rate of reaction is proportional to. Temperature Pressure Product of active masses Atomic mass
12 Law of mass action is applicable to. Reversible reaction Combustion reactions Irreversible reactions Endothermic reactions only
13 Law of mass action was proposed by  Le chatelier Arrheneius Guldberg and Waage Dalton
14 At equilirbium  Products dominate Reactants dominate Forward and reverse rates are zero Forward rate = reverse rate
15 Dynamic equilibrium occurs. In open systems Only in gases In closed systems Only at low temperature
16 Which is NOT a feature of dynamic equilibrium. Closed system Constant Temperature Uequal reaction rates No net change
