The transition temp.at which rhombic sulphur becomes monoclinic sulphur is
Number of coulombs of current required to convert completely 1 mole of MnO4- ions in acid medium to one mole of Mn2+ ions electrolytically is
Consider the two gaseous equilibria involving SO2 and the corresponding equilibrium constants at 298K
SO2(g)+1/2O2(g)⇔SO3(g);K1
2SO3(g)⇔2SO2(g)+O2(g);K2
The values of the equilibrium constants are related by
