Question

which of these is true for a voltaic cell? the reaction is non - spontaneous. the reaction cannot provide energy for work. the voltage is negative. there will be two separate compartments.

Explanation:

• For a voltaic (galvanic) cell: Reactions are spontaneous (so first option is wrong), they convert chemical energy to electrical energy to do work (second option wrong), cell potential (voltage) is positive (third option wrong). Voltaic cells have two separate compartments (anode and cathode) for the redox reactions to occur separately.

Answer:

D. There will be two separate compartments.
