LnK 20 10 0 -10 -20 -30 -40 -50 -60 -70 -80 -90 For an equilibrium reaction: K A + B the following graph was obtained. 0.002 TXT MIHI C + D Ink = 0.004 0.006 0.008 ЦИТ III 1/T -ΔΗΟ AS° + RT R 0.01 Given the above relationship, use the graph to identify which of the following statements are "true" or "false" in this specific case. All statements refer to the forward reaction (proceeding left to right, as given) corresponding to the equilibrium constant K. true The reaction is spontaneous at all temperatures. true ✓ As the temperature is increased, the equilibrium position shifts in favour of the reactants. true As the reaction proceeds, the system becomes less ordered. true The reaction is exothermic. false ✓ deltaGo is positive at low temperatures but becomes negative at higher temperatures. See Zumdahl, "Chemical Principles" 8th ed. Sec 10.11, p386 "The Temperature Dependence of K".
