34. a) State Le-Chatelier's principle and what is the effect of the change of temperature and pressure for the reaction.

$N_{2\left(g\right)} + 3H_{2\left(g\right)} \rightleftharpoons 2N{H}_{3\left(g\right)} ; ∆H = -92.4 KJ$

If the temperature was increased, the heat content of the system would increase, so the system would consume some of that heat by shifting the equilibrium to the left, thereby producing less ammonia... More ammonia would be produced if the reaction was run at a lower temperature, but a lower temperature also lowers the rate of the process...
