Answer:
ΔW = 1.168 × 10 ⁻²⁰ Joule
Explanation:
Given:
Change in Electric potential Δ V=Vout - Vin=0.073 V
Charge on sodium ions q = 1.6 ×10 ⁻¹⁹ C (+ve because of Missing one electron)
Work done by the electric fore when a sodium ions moves from outside to inside the cell is the change in the Electric potential energy Uout -Uin = ΔU
we have
ΔW =ΔU = q ΔV
ΔW = 1.6 ×10 ⁻¹⁹ C × 0.073 V
ΔW = 1.168 × 10 ⁻²⁰ Joule
