haber process

[mc-ducky]

which factors affect a reversible reaction, such as the haber process?

[squashBall]

pressure?

[north star]

3H2 + N2 = 2NH3

A high pressure would therefore move the equilibrium to the right giving you more of the product you want.

Temperature is also a factor and as the forward reaction is exothermic a high temperature would favour the backwards reaction. In practice a high temperature and and pressure are used as this gives the greatest rate of reaction and the highest yield of ammonia

[Cookaburra]

also if you continue to draw off the one of the products it will force the reaction in that direction
