Question

The temperature coefficient of e.m.f of a cell can be given by:, ∂ E ∂ T P = Δ S n F, ∂ E ∂ T P = E 2 - E 1 T 2 - T 1, ∂ E ∂ T P = Δ Η n F + E · 1 T, All of these

MARKS App · Accepted Answer

Δ G = Δ H + T ∂ Δ G ∂ T P (Gibbs-Helmholz equation) Also, Δ G = Δ H - T Δ S ; and - Δ G = n F · E or - T Δ S = T ∂ Δ G ∂ T P = T - n F ∂ E ∂ T P or ∂ E ∂ T P = Δ S n F , similarly derive for other values.
