In the following electrochemical cell : Zn(s)abs(zn^(+2)) abs(H^(+))Pt(H_(2)),E^(o)""_(cell) = E_(cell) This will be true when :

Answer»

<P>`[Zn^(2+)]=[H^(+)]=1 M and P_(H_(2))= 1 atm`
`[Zn^(2+)]=0.01 M,[H^(+)]=0.1 M and P_(H_(2))= 1 atm`
`[Zn^(2+)]=1 M,[H^(+)]=0.1 M and P_(H_(2))= 0.01 atm`
all of the above are TRUE
