Consider the following cell Pt|H2(P1 atm)|H+(M1)||H+(M2)|H2(P2 atm)|Pt – InterviewSolution

1.	Consider the following cell Pt\|H2(P1 atm)\|H+(M1)\|\|H+(M2)\|H2(P2 atm)\|Pt where P1 and P2 are pressures. M1 and M2 are molarities . What will be the emf of cell at 25∘C If P1=P2 and M1 is 50% higher than M2 ? Repeat the magnitude of emf by multiplying with 10000. [Take : 2.303RTF=0.06and log 3=0.48,log2=0.3]
Answer» Consider the following cell $P t \| H_{2} (P_{1} a t m) \| H^{+} (M_{1}) \| \| H^{+} (M_{2}) \| H_{2} (P_{2} a t m) \| P t$ where $P_{1}$ and $P_{2}$ are pressures. $M_{1}$ and $M_{2}$ are molarities . What will be the emf of cell at $25^{\circ} C$ If $P_{1} = P_{2}$ and $M_{1}$ is 50% higher than $M_{2}$ ? Repeat the magnitude of emf by multiplying with 10000. [Take : $\frac{2.303 R T}{F} = 0.06 and log 3 = 0.48, log 2 = 0.3]$
