| Rate $mol\,L^{-1}\,s^{-1}$ | $[A]$ $mol\,L^{-1}$ | $[B]$ $mol\,L^{-1}$ |
| $0.10$ | $20$ | $0.5$ |
| $0.40$ | $x$ | $0.5$ |
| $0.80$ | $40$ | $y$ |
What is the value of $x$ and $y ?$
$\Delta G_{f}^{o}\left(A g_{2} O\right)=-11.21\, kJ\,mol ^{-1}$
$\Delta G_{f}^{o}(Z n O)=-318.3\, kJ \,mol ^{-1}$
Then, $E^{o}$ cell of the button cell is.........$V$
$CO\left( g \right) + \frac{1}{2}{O_2}\left( g \right) \rightleftharpoons C{O_2}\left( g \right)$ is
