A student is given the electrochemical cell reaction:MnO4-(aq) + 8H+(aq) + 5e- → Mn2+(aq) + 4H2O(l)Calculate the standard potential (in volts) of the cell at 25°C given that the standard reduction potential of MnO4-(aq)/Mn2+(aq) couple and the standard reduction potential of the H+(aq)/H2(g) couple are +1.51 V and 0.00 V, respectively. The concentration of MnO4-(aq) is 0.010 M and that of H+(aq) is 1.00 M.

A chemistry experiment was conducted to determine the rate constant for the reaction between hydrogen peroxide and iodide ion in acidic medium. The initial concentrations of hydrogen peroxide and iodide ion were 0.2 M and 0.1 M respectively. The reaction was carried out at 25°C and the time taken for the completion of the reaction was 60 seconds. Based on these data, what is the rate constant for the reaction?
