The Gibbs-Helmholtz equation can be integrated to give eq. 2 (below) under constant pressure conditions, if ΔH is treated as constant: ΔrG(T2)/T2 = ΔrG(T1)/T1 + ΔH(1/T2− 1/T1 )Use eq. 2 to calculate Δ_rG∘ at 375 K for the reaction: 2CO(g)+O_2( g)→2CO_2( g) You will first need to determine the values of Δ_rG∘ and Δ_rH∘ at 298 K. Values for Δ_fH∘ and Δ_fG∘ at 298 K for CO,O_2, and CO_2 can be found in the appendix of your text.
