Use the standard reduction potentials located in the 'Tables' linked above to calculate the equilibrium constant for the reactio

Paladinen [302]

Answer:

Check the explanation

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 $1.35 \times 10^{16}$

Chlorine (cl) has an atomic number of 17. it often forms an ion by gaining 1 electron. what would its charge be?

Aliun [14]

Answer:

= -1

Explanation:

Chlorine belongs to the halogen group in the periodic table. It has an atomic number of 17, which indicates the number of protons and electrons in a neutral atom of chlorine is 17.
Therefore; with an atomic number of 17, its electronic configuration will be 2:8:7.
Thus; to attain a stable configuration chlorine requires to gain one electron, by so doing it becomes a negatively charged ion with a charge of -1.
