Chapter 12, Problem 12.66PAE
(a)
Interpretation Introduction
To determine:
Write chemical equations and equilibrium, expressions for the reactions of ammonia with water.
(a)
Expert Solution
Explanation of Solution
NH3(g)+H2O(l)→NH4+(aq)+OH−(aq)
Apply the concept
aA+bB⇌cC+dD
Rate of equilibrium reaction(K)=[C]c[D]d[A]a[B]b
So, here, rate of equilibrium reaction (K)=[NH4+][OH−][NH3][H2O].
In this equilibrium, water is pure liquid and its concentration is constant [H2O]=1
Dissociation constant (Ka)=[NH4+][OH−][NH3]
(b)
Interpretation Introduction
To determine:
Write chemical equations of equilibrium expressions for the reactions of methylamine. With water.
(b)
Expert Solution
Explanation of Solution
CH3NH2(aq)+H2O(l)→CH3NH3+(aq)+OH−(aq)
Apply the concept
aA+bB⇌cC+dD
Rate of equilibrium reaction (K)=[C]c[D]d[A]a[B]b
Rate of equilibrium reaction (K)=[CH3NH3+](OH−)[CH3NH2][H2O].
In this equilibrium, [H2O]=1
Dissociation constant (Ka)=[CH3NH3+](OH−)[CH3NH2]
(c)
Interpretation Introduction
To determine: Write chemical equations and equilibrium expressions for weak bases acetate ion C3COO− with water.
(c)
Expert Solution
Explanation of Solution
CHOO−(aq)+H2O(l)→CH3COOH(aq)+OH−(aq)
Apply the concept
aA+bB⇌cC+dD
Rate of equilibrium reaction (K)=[C]c[D]d[A]a[B]b
Rate of equilibrium constant is as (K)=[CH3COOH][OH−][CHOO−][H2O].
In this equilibrium, [H2O]=1
Dissociation constant (Ka)=[CH3COOH][OH−][CHOO−]
(d)
Interpretation Introduction
To determine: Write chemical equations and equilibrium expressions for hydrogen carbonate ion HCo3− with water.
(d)
Expert Solution
Explanation of Solution
HCo3−(aq)+H2O(l)→H2Co3(aq)+OH−(aq)
Rate of equilibrium constant for reaction
aA+bB⇌cC+dD
Rate of equilibrium reaction (K)=[C]c[D]d[A]a[B]b
Rate of equilibrium constant is as (K)=[H2Co3][OH−][HCo3−][H2O]
In this equilibrium, [H2O]=1
Dissociation constant (Ka)=[H2Co3][OH−][HCo3−]
[H2Co3][OH−]=Ka[HCo3−]
(e)
Interpretation Introduction
To determine: Write chemical equations and equilibrium expressions for aniline ion C6H5NH2 with water.
(e)
Expert Solution
Explanation of Solution
C6H5NH2(aq)+H2O(l)→C6H5NH3+(aq)+OH−(aq)
Apply the concept
Rate of equilibrium constant for reaction
aA+bB⇌cC+dD
Rate of equilibrium reaction (K)=[C]c[D]d[A]a[B]b
Rate of equilibrium constant is as (K)=[C6H5NH3+][OH−][C6H5NH2][H2O]
