In the reaction `1/2N_(2(g)) + 3/2 H_(2(g)) to NH_(3(g))`. The standard entropies of `N_(2(g)), H_(2(g)) and NH_(3(g))` are 191.6,130.5 and `192.5 JK^(-1) "mol"^(-1)` respectivly. If free energy charge of the reaction is -16.67 kJ. Calculate the `Delta H_("reaction")^@` for the formation of `NH_3` at 298 K.
