Balancing Redox Equations: Half-reaction?

I am having some problem with this question, which is: Basic solution Potassium permanganate, KMnO4, is a powerful oxidizing agent. The products of a given redox reaction with the permanganate ion depend on the reaction conditions used. In basic solution, the following equation represents the reacti...

Equilibrium concentration?

At 2000 degrees celcius the equilibrium constant for the reaction 2NO(g) equilibrium arrow N2 (g) + O2 (g) is Kc = 2.4x10^3. The initial concentration of NO is 0.150 M. a) What is the equilibrium concentration of NO? b) What is the equilibrium concentration of N2? c) What is the equilibrium concentr...

Rate law questions?

Consider the reaction of peroxydisulfate ion (S2O8^-2) with iodide ion (I^-) in aqueous solution: S2O8^-2(aq) + 3I^-(aq) → 2SO4^2-(aq) + I3^-(aq) At a particular temperature the rate of disappearance of S2O8^-2 varies with reactant concentrations in the following manner: Experiment S2O8^-2...
