Question

The equilibrium NH₃(aq) + H₂O(l) ↔NH₄⁺(aq) + OH⁻(aq) at 25 °C is subjected to a temperature jump which slightly increases the concentration of NH₄⁺(aq) and OH⁻(aq).

The measured relaxation time is 7.61 ns.

The equilibrium constant for the system is 1.78 × 10⁻⁵ at 25 °C, and the equilibrium concentration of NH₃(aq) is 0.15 mol dm⁻³.

k_rev = _____________. Just value in 3 sig. fig., in normal or exponential format, e.g. 1.16E6 meaning 1.16 x 10⁶ must use capital E. Choose a unit in the next question.
