Given that the reaction 2 Au" (aq) + 6 CT (aq)-2 Au (s) + 3 Ch (g) is spontaneous, which ONE of the following statements is FALSE? A) Au" (aq) is a stronger oxidizing agent than Clz (g). B) Au" (aq) oxidizes Cl (aq). C) D) E) CH (aq) reduces Au" (aq). 6 electrons are transferred in the above reaction. CI (aq) is a weaker reducing agent than Au (s).

The combustion of acetylene is used in welder's torches because it produces a very hot flame: 5 C₂ H2(g) + O2(g) → 2 CO₂ (g) + H₂O(g) AH = -1255.5 kJ Substance Sº (J mol-¹ K-¹) C₂ H₂(g) 200.8 O₂(g) CO₂(g) H₂O(g) 205.0 213.6 188.7

3.65 g of zinc metal react according tyo the following reaction at 25 C. Is this reaction spontaneous?  Zn (0 + 2H^+ (aq) -> zn^2= (aq) + H2 (g)

How would I solve this question?

Consider the dissolution of nitrous acid: HNO₂(aq) For this reaction under standard conditions, AG° = 19.1 kJ/mol. Calculate A Gat 298 K, when [H*] = 5.0×10-² M, [NO₂¯] = 2.0×10−³ M and [HNO₂] = 0.10 M. (A) 2.0 kJ/mol (B) 12.5 kJ/mol (C) 16.6 kJ/mol (D) 19.1 kJ/mol (E) 36.2 kJ/mol - H+ (aq) + NO₂ (aq).

Determine AG (in kJ) for the following reaction at 325 K when the concentrations of the species are as follows: NO₂= 10.00 M, N₂O4 = 14.3 M. AG°f (NO₂) = 51 kJ/mol, AG (N₂O4) = 97.7 kJ/mol. 2 NO2(8) N₂O4(8)
