1.	What are neutral oxides? Explain the nature of zinc oxide with the help of reaction. Define Molar Conductivity and Zero order reaction. In a first order reaction x `to` 40% of the given sample of compound rate constant of the reaction.
Answer» The oxides which are neither acidic nor basic are called as neutral oxides. Ex. NO,CO,`N_(2)O` etc. Amphoteric natural of ZnO `ZnO_((s)) + 2HCI_((aq)) to ZnCl_(2(s)) + H_(2) O_((1))` `ZnO_((s)) + 2 NaOH_((aq)) to Na_(2) ZnO_(2(aq)) + H_(2) O_((1))` Molar conductivity : The conductance of a volume of a solution containing 1 mole of dissolved electrolyte when placed between two parallel electrode 1 cm apart. Zero order reaction : The reaction whose rate is independent of the reaction concentration adn remains constant throughout the course of the reaction. Solution : At t = 45 concentration `[A]_(0) = 100` final concentration `[A]_(r ) = 40` `K = (2.303)/(t) log_(10) ([A]_(0))/([A]_(t))` `= (2.303)/(45) log_(10) (100)/(40)` `= (2.303)/(45) log_(10) 2.5` `= (2.303 xx 0.3979)/(45)` `= 0.02036 "min"^(-1)`
