Consider a thermodynamically spontaneous cell at 298 K composed of 100. mL of 1.0 M Fe^2+(aq) in one beaker with an iron electrode and 100. mL of 1.0 M Mn^2+(aq) in another beaker with a manganese electrode. The beakers are connected with a porous disc and the electrodes are connected with a wire connected to a voltmeter: Fe^2+(aq) + Mn(s) → Mn^2+(aq) + Fe(s) E° = +0.74 V Qualitatively describe the effect on the value of Q and the voltage when the following changes occur: A) 0.10 moles of Fe(NO3)2 is added to the Fe^2+(aq) beaker
