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.
(c) Calculate the rate constant for the reverse reaction.
krev = _____________. 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. .
