Explain styrene is produced by catalytic dehydrogenation

Reference no: EM13310577

Styrene is produced by catalytic dehydrogenation of ethylbenzene at high temperature in the presence of superheated steam. A.) Given the following data, what is the delta Hrxn, delta Grxn and delta Srxn at 298 K. Ethylbenzene, C6H5--CH2CH3 : delta Ht = -12.5 kJ/mol, delta Gt = 119.7 kJ/mol and S = 255 J/mol*K Styrene, C6H5--CH==CH2 : delta Ht = 103.8 kJ/mol, delta Gt = 202.5 kJ/mol and S = 238 J/mol*K B.) At what temperature is the reaction spontaneous?
