Question

Please show work step by step and answer.

The Temperature Dependence of Chemical Equilibrium For an equilibrium reaction: - A+B Kc+o the following graph was obtained. 0.002 0.008 0.01 0.004 0.006 1/1 InK = -AHO + 4,50 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. The reaction is endothermic. deltaGº is positive at all temperatures. As the temperature is decreased, the equilibrium position shifts in favour of the products. As the reaction proceeds, the system becomes less ordered. The reaction is spontaneous at all temperatures. See Zumdahl, "Chemical Principles" 8th ed. Sec 10.11, p386 "The Temperature Dependence of K".

Answer 1

lnk. enka. Ako (7) + 450 slope of the line = - DHO since slope of the graph is the intercept on the graxis is positive that means anave. that means AS = the ② Since H ove, that means the reaction is exothermic. The reaction is endothermic. False ③ AG AH-TASO; Snicu AH-ve and AS atve, Ago would be negative at all temperatures. Ago is positive at all temperatures. False] As temperature in decreases, (h) increases and so does the k. (equilibrium constant increases). As the temperature is decreased, the equilibrium position shifts in favor of the products. [True 4 As the reaction proceeds, as = the and entopy of system increases so randomness increases. (l.e. lens ordered). As the reaction proceeds, the system becomes less ordered [True] & The reaction is spontaneous at all temperatures. True
