Question

JEE Mains Chemistry question is in the image

Answer 1

ANSWER :- 144.

EXPLANATION :-

$\rightarrow \: E°cell = E°Cu^+/cu - E°cu {}^{ + 2} /Cu {}^{ + 1} \\ \\ = 0.52 - 0.16 \\ \\ = 0.36v$

We know,

$\rightarrow \: ✪ \boxed{E°cell = \frac{ RT }{nF} ln \: keq} \\ \\ \implies0.36 = \frac{0.025}{1} ln \: k \\ \\ \implies \: ln \: k \: = 14.4 = 144 \times {10}^{ - 1} = 144$

Hence , the answer is ,

$\\ \\ \rightarrow \: \boxed{ln \: k \: = 144}$
