Assertion: `Ni//Ni^(2+)(1.0M)||Au^(3+)(1.0M)|Au`, for this cell emf is 1.75V if `E_(Au^(3+)//Au)^(o)=1.50` and `E_(Ni^(2+)//Ni)^(o)=0.25V` Reason: Emf of the cell `=E_("cathode")^(o)-E_("anode")^(o)`A. if both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is falseD. If the assertion and reason both are false. |

Answer» Correct Answer - A Both assertion and reason are true and reason is the correct explanation of assertion. `E_(Au^(3+)//Au)^(@)-E_(Ni//Ni^(2+))^(@)=1.50-(+0.25)=1.25V` |
