19 for the reaction n,(g)+3h, (g)>2nh,(g) compute the entropy change (in j/ki/ mol) for the process comment on the sign of the property. data: species n,() 191.

19 For the reaction N,(g)+3H, (g)>2NH,(g) Compute the entropy change (in J/KI/ mol) for the process comment on the sign of the property. Data: Species N,() 191.5 H,() 130.6 NH,() S(J/K/mol) 192.3 (a) AS°=-37.65 J/k/mol, negative sign indicates that there a decrease in the gaseous species during the reaction. (b) AS°=-198.7 J/k/mol, negative sign indicates that there a decrease in the gaseous species during the reaction. (c) AS°=-31.25 J/K/mol, negative sign indicates that there a decrease in the gaseous species during the reaction. (d) As° = +31.25 JK/mol, the positive sign indicates that there reaction is spontaneous.
