A learner claims that iron and copper can be used to make a voltaic cell but not an elec- trolytic cell because a spontaneous reaction occurs between the two metals. What is the most appropriate response? A The learner is correct. B The learner is incorrect because an electrolytic cell can be made by using a power sup- ply to run the reaction in the nonspontaneous direction. C The learner is incorrect because no spontaneous reaction occurs between iron and cop- per, and only an electrolytic cell can be made with these two metals. D The learner is incorrect because an electrolytic cell can be made by simply connecting the iron and copper electrodes with a wire.
