Thermodynamics/Equilibrium Connection

Question 1

Van’t Hoff Equation

Answer 1

ln[Kp2/Kp1] = -ΔHrxn•/R [1/T2 - 1/T1]
Establishes relationship between Kp1 (equilibrium constant for reversible reaction at Kelvin T1) and Kp2 (equilibrium constant for reversible reaction at Kelvin T2)

Question 2

Linearized Equation specifying dependence of K on Tkelvin

Answer 2

LnK = -ΔH/RT (1/T) + ΔS/R
