Answer to Question #321357 in General Chemistry for TJW

Question

A hypothetical reaction to form the compound A3B2 from its constituent elements is shown 

below. 

A2 (g) + B2 (g) → A3B2 (l) ∆H = –13.4 kJ/mol AB3 ∆S = –84.3 J/mol∙K 

Calculate the change in free energy (∆G) for this reaction at 298 K (25 °C, “room temperature”) using the formula ∆G = ∆H - T∆S. 

Answer 1

11.72 kJ/mol
