For spontaneity of a cell, which is correct.

A

>ΔEo> \Delta E^{o}

B

=0= 0

C

<ΔEo< \Delta E^{o}

D

27oC27^{o}C

Answer

27oC27^{o}C

Explanation

Solution

(R=2)(R = 2); PCl5(g)→PCl3(g)+Cl2(g)PCl_{5}(g) \rightarrow PCl_{3}(g) + Cl_{2}(g)

For spontaneity ΔH=ΔE\Delta H = \Delta E

ΔH>ΔEΔH<ΔE\Delta H > \Delta E\Delta H < \Delta E, (H)(H)
