a) Equilibrium can be established only in closed system.
b) Chemical equilibrium is dynamic in nature.
 
2 The value of Kc = 6.2 at 750K for the reaction CO(g) + H2O(g) ⇌ CO2(g) + H2(g). If initially the quantities of CO and H2O are 2 moles in a 1 liter vessel, What would be the equilibrium concentrations of all the chemicals?
 
3 The Kc value for the reaction SO2 (g) + ½ O2 (g) ⇌ SO3 (g) is 72.5. What is the value of Kc for 2SO3(g) ⇌ 2SO2(g) + O2(g)?
 
4 If the Kp value for the reaction CO2(g) + C(s) ⇌ 2CO(g) at 1000K is 3, find value of Kc.
 
5 An equilibrium mixture contains [PCl5] = 0.15 ; [PCl3] = 0.29 ; [Cl2] = 0.32. If Kc for the dissociation of PCl5 at the same temperature is 3.5, in which direction is the reaction proceeding?
 
6 What happens to the concentration of products when the pressure is increased in the following reaction at equilibrium? 2NO2(g) ⇌ N2O4(g)?
 
7 Calculate the degree of dissociation, pH, and concentration of all species at equilibrium of a 0.05M HCN solution if Ka = 4.9 x 10-10.
 
8 If Ka for the weak acid niacin is 1.5 x 10-5, what is Kb for its conjugate base?
 
9 The pH of an acetic acid solution is 5.6. What is the concentration of the solution if Ka = 1.8 x 10-7?
 
10 Name an acid buffer and an alkaline buffer each.
 
11 Copper is precipitated as sulphide in the II group while Zn is precipitated as sulphide in the IV group. Explain.
 
12 What is basic principle behind the systematic analysis of cations and group separation? Explain.
 
13 Differentiate between
a) hydrolysis and hydration
b) solubility and solubility product
 
14 Calculate the solubility of BaSO4 if its Ksp value is 1.1 x 10-10
 
15 10ml of 0.1M CaCl2 is mixed with 15ml of 0.11M NaF. Predict whether CaF2 will precipitate if the Ksp of CaF2 is 5.3 x 10-9.
 
16 Which of the following is more soluble?
a) AgCl or AgBr [ Ksp of AgCl = 1.8 x 10-10 ; AgBr = 5 x 10-13]
b) AgCN or Ni(OH)2 [ Ksp AgCN = 2 x 10-15; Ni(OH)2 = 6 x 10-17]
 
17 State (i) Henry’s law (ii) Law of mass action (iii) LeChatelier’s principle
 
18 Classify the following as Lewis acid or Lewis base
H+ , H2O , NH3 , BF3 , Al3+ , BeCl2 , Cl-
 
19 Write the formula for the conjugate acid of
(i) F- (ii) OH-
 
20 Write the formula for the conjugate base of HNO2 , HClO4 , OH-
 
21 A buffer solution contains 0.4mol of ammonium hydroxide and 0.5mol of ammonium chloride to make a buffer solution of 1L.Calculate the pH of the resulting buffer solution. Dissociation constant of ammonium hydroxide at 25oC is 1.81x 10-5
