12. A sample of CH3CH2NH2 is placed in an insulated container, where it decomposes into ethene and ammonia according to the reaction represented below. HH Substance S* 0/(mol-K)) 1 CH3CH2NH2(g) 284.9 H-C-C-N-H + CH2CH2(B) 219.3 NH3(g) 192.8 a) Using the data in the table above, calculate the value, in J/(molo-K), of the standard entropy change AS, for the reaction at 299K. [1 mark] -11-H1 b) Using the data in the table below, calculate the value, in kl/molen, of the standard enthalpy change, AH", for the reaction at 298K. [2 marks) Bond C.c CC CH C-N N-H Average Bond Enthalpy (kl/mol) 348 614 413 293 391 c) Based on your answer in part (b), predict whether the temperature of the contents of the insulated container will increase, decrease, or remain the same as the reaction proceeds. Justify your prediction. [1 mark]
