Q82 · Chemistry

For a cell involving one electron Ecell⊖=0.59E^\ominus_{cell} = 0.59 V at 298 K, the equilibrium constant for the cell reaction is :

[Given that 2.303 RTF=0.059\frac{2.303\ RT}{F} = 0.059 V at T = 298 K]

  1. 11.0×1021.0\times10^{2}
  2. 21.0×1051.0\times10^{5}
  3. 31.0×10101.0\times10^{10}Official answer
  4. 41.0×10301.0\times10^{30}

Official answer: option 3 · NTA final answer key
