Redox Reactions And Electrochemistry Ques 648

Question: The emf of the cell Pt,Cl2(g)(P1atm)/Cl(aq) (1M)/Cl2(g)(P2atm)Pt will be positive when

Options:

A) P1=P2

B) P1<P2

C) P1>P2

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

[b] The cell reaction is Cl2(g)(P2atm)Cl2(aq)(P1,atm)

Ecell=0.05922logP1P2=0.05922logP2P1

Ecell will be positive when P2>P1.
