For the reaction below, describe the temperature and pressure conditions that would produce the highest yield of the forward reaction. Explain your answer in terms of Le Châtelier’s principle.

N2O4 (g) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. 2 NO2 (g) deltaH = +57.2 kJ/mol

aaronq · Answer

A + heat <-> 2B 

T: up to the right (because endothermic); down to the left
P: up to the left because less moles; down to the right because more moles
