(a) Arrrange A,B,C and D in order of incresing electrode potential in the electrochemical series if (i) A+B^(+)rarrA^(+)+B,(ii) B +D^(+) rarr B^(+)+D (iii) B+C^(+)rarrB^(+)+C,(iv) C^(+)+Drarr NO reaction (b) on the basisof the above data predict which of the following reaction will ocur (i) A+C^(+) rarrA^(+)+C, (ii) A^(+)+D rarrA+D^(+)
