NEET 2013 - Question 171


A button cell used in watches functions as following $$Zn(s)+Ag_{2}O(S)+H_{2}O(l) \rightleftharpoons 2Ag(s)+{Zn}^{2+} (aq)+2{OH}^{-}(aq)$$
If half cell potentials are $${Zn}^{2+}(aq)+2e^{-}\rightarrow Zn(s);E^\circ = -0.76V$$
$$Ag_{2}O(s)+H_{2}O(1) + 2e^{-}\rightarrow 2Ag(s)+2OH^{-} (aq), E^\circ =-0.34V$$
The cell potential will be:
