JEE MAIN - Chemistry (2020 - 5th September Morning Slot - No. 13)
An oxidation-reduction reaction in which
3 electrons are transferred has a $$\Delta $$Gº of 17.37 kJ mol–1 at
25 oC. The value of Eo
cell (in V) is ______ × 10–2.
(1 F = 96,500 C mol–1)
3 electrons are transferred has a $$\Delta $$Gº of 17.37 kJ mol–1 at
25 oC. The value of Eo
cell (in V) is ______ × 10–2.
(1 F = 96,500 C mol–1)
Answer
-6
Explanation
$$\Delta $$Gº = 17.37 kJ ; n = 3
$$\Delta $$Gº = -nF$$E_{cell}^o$$
$$ \Rightarrow $$ $$E_{cell}^o$$ = $$ - {{17.37 \times 1000} \over {3 \times 96500}}$$
= -0.06 = -6.00 $$ \times $$ 10-2
$$\Delta $$Gº = -nF$$E_{cell}^o$$
$$ \Rightarrow $$ $$E_{cell}^o$$ = $$ - {{17.37 \times 1000} \over {3 \times 96500}}$$
= -0.06 = -6.00 $$ \times $$ 10-2
