Hi please help me with my homework thank you For each scenario, identify if the entropy change of the process is positive or negative.
Entropy Example: If AS°¸ =-198.3 J/K, is the reaction spontaneous at 25°C sys N2 + 3H2 → 2NH3 • AS univ = AS sys + AS surr > ? • AS surr =-(AHsys)/T Determine the AHrxn • AH˚4 N2(g) = 0 kJ/mol f • AH°+ H2(g) = 0 kJ/mol f • AH° NH 3(g) = -46.19 kJ/mol f
