[4%] Use Hess's Law to calculate the standard enthalpy change for the reaction, AH,, using the thermochemical data provided below (at 298 K): AH / kJ mol-¹ Molecule -359.2 C₂H₂OH CO2 (g) -393.5 -241.8 H₂O (9) 0 O2 (g) (f) The standard entropy change for this reaction, AS,, is 379 J K-¹ mol-¹. Does this value indicate that the entropy of the system increases or decreases for the forward reaction? [1%] (g) Calculate the change in Gibbs energy for the reaction, AG,, at 298K. Use your value to predict whether the forward reaction is a spontaneous process. [3%]
