Test: MCAT Physical

A student conducts an experiment for a chemistry class. The student wishes to explore power generation from different types of voltaic cells. He sets up three different cells, and then compares the amount of energy generated from each one.

One of his cells is shown below as an example. Both remaining cells follow the same layout. 



The student in the passage disassembles the cell, and attempts to rebuild it the next day. He forgets, however, to include  in the solvent of the half cell on the right side of the diagram. Which of the following is likely to happen?

The cell requires , not , in the right-side half reaction to function properly

The cell will not function at all

The cell will function, but for a shorter period of time before it reaches equilibrium and ceases to produce energy

The cell will function without pre-existing in solution, but not without 

The cell will produce more energy, because there is no existing ion to repel further ionization into solution
