Rate constants for the forward and reversed steps.
The equilibrium NH3(aq) + H2O(l) NH4(aq) + OH(aq) at 25C is subjected to temperature jump that slightly increases the concentration of NH4(aq) and OH(aq).The measure relaxation time is 7.61 ns. The equilibrium constant for the systems is 1.78x10^-5 at 25C, and the equilibrium concentration of NH3(aq) is 0.15mol/dm^3. Calculate the rate constants for the forward and reverse steps.Hint: Answers are 1.28x10^4 dm^3/mol-sand4.0x10^10 dm^3/mol-s
