Gce Model Questions Vol1 2025 Chemistry Question 32
Practice objective / multiple choice question 32 from the 2025 Gce Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed with the half‑cells Fe³⁺/Fe²⁺ (E° = +0.77 V) and Cu²⁺/Cu (E° = +0.34 V). The Fe half‑cell contains 0.020 M Fe³⁺ and 0.10 M Fe²⁺; the Cu half‑cell contains 0.050 M Cu²⁺. At 298 K, determine (i) the cell EMF and which electrode acts as the anode, and (ii) the equilibrium constant K for the overall cell reaction. Give E_cell to three significant figures and K in scientific notation to two significant figures.
