Question #26863

Answer 1

Your reactions are

`"NH₄⁺(aq) → NO₂⁻ (aq); " k_s = "6 h⁻¹"`

`"NO₂⁻(aq) → NO₃⁻(aq); " k_b = "6 h⁻¹"`

For easier typing, let's re-write them as

`"NH₄⁺ " stackrel("k₁")("→") " NO₂⁻ " stackrel("k₂")("→") " NO₃⁻"`

The differential rate laws for the formation of each component are then:

`(d["NH₄⁺"])/dt = -k_1["NH₄⁺"]`

`(d["NO₂⁻"])/dt = k_1["NH₄⁺"] – k_2["NO₂⁻"]`

`(d["NO₃⁻"])/dt = k_2["NO₂⁻"]`
