Answer 1

ower 1. E a Saturated solution (in saturated Soluton both Solute in Solid State and solute in solution is in dynamic equiliborom) as - Solate (5) Ź Solate (aa) (2 0 The solubility of a solid is highly dependent on temperature (for solide solubility only depends on temperature) (6) © Decrease the temperature and raise the pressure (decreasing temperature ready to reduction in Kinetic energy of gas molecule so they liquefied easily) 6 for frugt order reaction gay AKB Rate = KLA Here rate is directly proporrenal to reactant A (E) Not Oz - No2to2 Rate = k [NO] [03]1/2 order = 1+ I 2 1.5 (G) 6 Bensone is a non-polar golvent i so it will dinclue only non-polar solute Now 3 C5H12 ( peutane) is algo non-polan ; so it is most Soluble in beusone
