Explain the need for a temperature compromise in the Haber Process: N2(g) + 3 H2(g) ⇌2 NH3(g) (ΔH = -92 kJ mol-1)

The Haber process is used to produce ammonia (NH3), so we want the equilibrium position to be as far over to the right hand side of the equation as possible to maximise the yield of NH3. As the enthalpy f...
