The selectivity coefficient for a fluoride ion-selective electrode is K^pot F^-.OH^- = 0.15. What will the change in the electrode potential be for a 1.4 times 10^-5 M F^- at pH 5.5 if the pH is raised to pH 11.0?

Is this a single replacement reaction or there is no

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
