Question

he ^⁰ values of KNO₃ and LiNO₃ are 145.0 and 110.1 Scm² mol⁻¹ respectively. The λ⁰ value

for K⁺ ion is 73.5 S cm² mol⁻¹. Calculate λ⁰ (Li⁺).​

Answer 1

Answer:

∵ LiCl.3NH3(s)⇌LiCl.3NH3(s)+2NH3(g)

                                                                            [Kp=9atm2]

LiCl.3NH3(s)+2NH3⇌LiCl.3NH3(s)

                                                     [Kp1=91atm−2]

0.1                     (a + 0.2)                            Initial moles

0                         a                              0.1 Final Moles at equilibrium

∴ Initial moles of NH3 should be (a+0.02) to bring in completion of reaction.

At

equilibrium Kp1= (PNH3′)21 or 91

=(PNH3′)21

∴PNH3′ = 3 atm

∵ PV=nRT

∴ 3
