Consider the following reaction, `Cu|Cu^(2+) (1M)||(Zn^(2+)(1 M)|Zn` A

1.	Consider the following reaction, `Cu\|Cu^(2+) (1M)\|\|(Zn^(2+)(1 M)\|Zn` A cell represented above should have emfA. positiveB. negativeC. zeroD. Cannot be predicted
Answer» Correct Answer - B If `E_(red)^(@)` of `Cu` and `Zn` are known from `ECS`. then, `E^(@)=E_("cathode")^(@)-E_("anode")^(@)` `=E_("right")^(@)-E_("left")^(@)` `=(-0.76)-(+0.34)` (From ECS) `=-0.76-0.34=-1.10 V`
