Explanation:

cell CuE Ecell 0.337 (-0.14) Ecl0.477 V

Since $E^o_{ cell } > 0$ , the value of \Delta G^o will be negative.

$\Delta G^o < 0$

$\Delta G^o =-nFE^o_{ cell }.$ .....(1)

But

$\Delta G^o =-RT ln K$ ......(2)

From (1) and (2)

$\Delta G^o =-RT ln K=-nFE^o_{ cell }$

ln K = $\frac{nFE^o_{ cell } }{RT }$

ln K = $\frac{ 2 \times 96500 \times 0.477 }{8.314 \times \left ( 25+273.15 \right ) }$

ln K =37.139

K = $1.3468 \times 10^{16}$

Hence, the value of the equilibrium constant is $1.35 \times 10^{16}$

levacccp [35]

Answer:

A. An atom

Explanation:

A large scale model is one that is bigger than the object itself. These are needed to visualise structures and behaviours that we cannot normally see. A large scale model is needed for small objects, such as an atom. Larger objects do not need<em> even bigger</em> models
