The Haber Process for the manufacture of ammonia from nitrogen and hydrogen involves this reversible reaction. In order to get the maximum possible percentage of ammonia in the equilibrium mixture, would you choose to use a high or a low temperature? N2(g)+3H2(9)2NH3(9)H=92kJmol1 You would choose a high temperature. Increasing the temperature, according to Le Chatelier, will cause the reaction to move in such a way as to increase it again. You would choose a low temperature. Lowering the temperature, according to Le Chatelier, will cause the reaction to move in such a way as to increase it again. You would choose a high temperature. Increasing the temperature, according to Le Chatelier, will cause the reaction to move in such a way as to increase it further. You would choose a low temperature. Lowering the temperature, according to Le Chatelier, will cause the reaction to move in such a way as to lower it further
