Concept explainers
(a)
Interpretation:
Whether for the given reaction, the value of Keq is large number or small number should be determined and for this reaction whether the reactant is more or product is more at equilibrium should be determined.
NH3+H2O→NH+4+OH−
Concept Introduction:
A substance which produces H+ or proton when dissolved in aqueous solution is known as an acid. These are proton donor.
A substance which produces hydroxide ion when dissolved in aqueous solution is known as a base. These are proton acceptor.
A
The value that defines the relationship between the amount of products and reactants at equilibrium is known as equilibrium constant.
(b)
Interpretation:
Whether the answer in part (a) is consistent with the energy diagram for the reaction should be determined.
Concept Introduction:
A substance which produces H+ or proton when dissolved in aqueous solution is known as an acid. These are proton donor.
