E ₁, E ₂, E ₃ are the emf values of the three galvanic cells respectively.

Step-by-step solution

For the given cell, E _ cell = E _ cell ^ - 0.0591 2 [ Zn ²⁺ ] [ Cu ²⁺ ] (i) aligned E ₁ &= E _ cell ^ - 0.0591 2 1 0.1 &= E _ cell ^ - 0.0591 2 aligned (ii) E ₂= E _ cell ^ - 0.0591 2 1 1 = E _ cell ^ - 0.0591 2 0 = E _ cell ^ (iii) E ₃= E _ cell ^ - 0.0591 2 0.1 1 = E _ cell ^ + 0.0591 2 E ₃> E ₂> E ₁
