12) If the E_(equ) value of galvanic cell below is 1.50 V. What should be the concentration of [Ag'] Zn(s)vert Zn^+2(0.018M)Vert Ag^+(ldots M)vert Ag(s) (E^0Zn^ast /n.a^m-0.763V;E^circ Ag'/A_(E)=0.799V) A) 0.009M B) 0.012 M C) 0.016 m D) 0.024 M E) 0.083 M

To find the concentration of in the given galvanic cell, we can use the Nernst equation. The Nernst equation relates the cell potential to the concentrations of the reactants and products.The Nernst equation is given by: where is the cell potential, is the standard cell potential, is the number of moles of electrons transferred, and is the reaction quotient.In this case, the standard cell potential ( ) can be calculated as: The reaction quotient ( ) is given by: We are given that and . We need to find .Substituting the values into the Nernst equation: Solving for , we get: Therefore, the correct answer is D) 0.024 M.
