For the above cell — Electrochemistry Chemistry Question

💡 Solution & Explanation

In the given cell, the reduction occurs at the cathode (RHS, 1 M) and oxidation at the anode (LHS, 0.05 M). Since ions spontaneously move from a region of higher concentration to lower concentration, the overall process is spontaneous. A spontaneous cell reaction possesses a positive cell potential (E_cell > 0) and a negative free energy change (ΔG < 0). Therefore, correct answer is B.
