Answer by appropriately matching the information given in the three columns of the following table:

For the cell given in column-I, the only correct combination is:

Answer:

Solution:

$E_{cell} = E^{o} - 0.059 pH$

$= 0.7 - 0.059 \times 2 = 0.582 V$

Since $E_{cell}$ is +ve, so reaction is exergonic (i.e. $Δ G = - ve)$
