The reaction OH(aq) + HCN(aq) H2O(l) + CN(aq) is first-order in both the OH and HCN concentrations. The rate constant at 25oC is 3.7×10^9 mol^-1 L s^-1. In an experiment, 0.500 L of 0.020 mol L ^-1 NaOH(aq) is rapidly mixed with an equal volume of 0.020 mol L^-1 HCN(aq). Calculate the time, in seconds, required for this [OH] to decrease to 1.0×10^4 mol L^1. (Hint: Start from the rate law in the form Rate = k [HCN ]^n[OH]^m
