QNEET-2023-Ch-273: NEET 2023 Chemistry - Class 12 NEET-2023-Ch-273 Solution: The correct value of cell potential in volt for the reaction…

The correct value of cell potential in volt for the reaction that occurs when the following two half cells are connected is Fe2+(aq)+2e−→Fe(s)E∘=−0.44 VFe^{2+}(aq) + 2e^- \rightarrow Fe(s) E^\circ = -0.44\ \text{V} Cr2O72−(aq)+14H++6e−→2Cr3++7H2O E∘=+1.33 VCr_2O_7^{2-}(aq) + 14H^+ + 6e^- \rightarrow 2Cr^{3+} + 7H_2O\ E^\circ = +1.33\ \text{V} +1.77 V +2.65 V +0.01 V +0.89 V

Multiple Choice Options

  • A +1.77 V+1.77 \mathrm{~V} + 1.77   V
  • B +2.65 V+2.65 \mathrm{~V} + 2.65   V
  • C +0.01 V+0.01 \mathrm{~V} + 0.01   V
  • D +0.89 V+0.89 \mathrm{~V} + 0.89   V

Step-by-Step Verified Solution

E cell  _ = E C o _ E A o = ( 1.33 ) _ ( _ 0.44 ) = + 1.77   V
