(1) Use the thermodynamic values to (a) deduce the enthalpy change of each reaction (b)state if the reaction is exothermic,or endothermic,and also how much energy is released or absorbed. For thi reactions; (1) NH4NO3 (s)------>N2 (g) + 2H2O (l) (2) 4Zn (s) + 9HNO3 (aq)------->4Zn(NO3)2 (aq) + NH3 (g) 3H20 (l) (2) Predict the shift in equilibrium,if additional energy is added to the chemical reactions (1) and (2) above seperately.
