Ecello= 1.1 V for Daniel cell. Which of the following expressions are correct descriptions of the state of equilibrium in this cell?

(a) 1.1 = KC

(b) 2.303RT2FlogKC=1.1

(c) logKC=2.20.059

(d) log KC = 1.1

The correct choice among the given is -

1. (a, b)

2. (b, c)

3. (c, d)

4. (a, d)


At state of equilibrium
ΔG=-RT logK
-nFE°=-RT 2.303 logKC
                                          E=+RT 2.303 logKC+2F             (n=2 for Daniel Cell)
 At equilibrium E° =1.1
2.303RT2FlogKC=1.1
                                            logKC=2.20.059                            [on solving]
Hence, options (b) and (c) are the correct choices.
