1) Which is strongest redicing agent
E) Na(s)
Standard reduction potential of Na+ to Na ( -2.71V) is lower than other species , so it act as strogest reducing agent.
2) Which is weakest oxidizing agent
D) K+ (s)
standard reduction potential of K to K+ (-2.831V) , so reducing ability of K+ to K is lower than other species , so K+ act as weakest oxidizing agent
3) Which is weakest reducing agent
C) Ba2+(aq)
Ba2+ is already completely oxidised , so it will not further oxidise
4) Which pair give spontaneous reaction at 25℃
D) Ag+(aq) + Br-(aq)
Note : actually , C and D both pairs gives spontaneous reaction at 25℃ but if single choice is the answer then D is the answer.
