The following reaction has Kc > 1: Ni(H2O)62+(aq) + 6 NH3(aq) → Ni(NH3)62+(aq) + 6 H2O(l) Based on this information, what can you conclude about the strength of NH3 as a Lewis acid/base? Select all that apply. Group of answer choices NH3 is a stronger Lewis base than H2O NH3 is a weaker Lewis base than H2O NH3 is a stronger Lewis acid than H2O NH3 is a weaker Lewis acid than H2O

Respuesta :

Answer : The correct option is, [tex]NH_3[/tex] is a stronger Lewis base than [tex]H_2O[/tex]

Explanation :

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

As we are given that :

Kc > 1 this means that the reaction is favored in forward direction. That means,

[tex]NH_3[/tex] can readily lose electrons and act as a lewis base which has excess of electrons and a stronger base.

[tex]H_2O[/tex] can readily accept electrons and act as a lewis acid.

Hence, the correct option is, [tex]NH_3[/tex] is a stronger Lewis base than [tex]H_2O[/tex]
