As you have told in the answers to my earlier question, if I neutralise aqua regia with a 1:3 mixture of NaOH and KOH, then as it is itself a 1:3 mixture of HNO₃ and HCl, does it form a double salt (NaNO_3.3KCl) with 4 H₂O molecules or two individual salts (NaNO₃ & 3KCl) with 4 H₂O molecules?

    The reaction   2A + 3B        C is first order with respect to A and B. When the initial concentrations are [A] = 1.6 x 10-2 M and [B] = 2.4 x 10-3 M, the rate is 4.1 x 10^-4 M/s. Calculate the rate constant of the reaction. (5 points)
