According to the given ion-molecular equation of the current-forming reaction:
2MnO4- 5H2S 6H = 2Mn2 5S 8H2O,
write the equations for the anodic and cathodic processes. Calculate the value of the standard, equilibrium constant of this current-generating reaction, if the values of the standard electrode potentials φ0 are equal to 1.51 and 0.17 V
