1.	When the total cell emf of a voltaic cell is greater than zero, which of the following is true about the reaction quotient Q and free energy change `DelatG` for the cell reaction ?A. Q is less than one and `DeltaG` is greater than zeroB. Q greater than one and `DeltaG` is greater than zero.C. Q is less than one and `DeltaG` is less than zero.D. Q is greater than one and `DeltaG` is less than zero.
Answer» Correct Answer - C (c ) `DeltaG=DeltaG^(@)+RT" In "Q` It `E_(cell)` is +ve,`DeltaG` is -ve (Cell working is feasible) Similarly `E_(cell)` is -ve, `DeltaG^(@)` is -ve. `:. RT " In "`Q is also -ve or `Q lt t`.
