Transition metal and their compounds are used as catalysts in industry and in biological system. For example, in the Contact Process, vanadium compounds in the + 5 state (V_2O_5 or VO_3^(-)) are used to oxidise SO_(2) " to "SO_3 : SO_(2) + 1/2O_2 overset(v_2o_5) rarr SO_(3) It is thought that the actual oxidation process takes place in two stages. In the first step, V^(5+) in the presence of oxide ions converts SO_(2)"to " SO_3 ' At the same time, V^(5+) is reduced to V^(4+) 2V^(5+) + O^(2-) + SO_(2) rarr 2V^(4+) + SO_(3) In the second step V^(5+_ is regenerated from V^(4+) by oxygen : 2V^(4+) + 1/2 O_(2) rarr 2V^(5+) +O^(2-) The overall process is, of course, the sum of these two step : SO_(2) + 1/2 O_(2) rarr SO_(3) Which of the following ion involved in the above process will show paramagnetism?
