Within the Haber process, an equilibrium is set up. $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g)$ The forward reaction gives out heat. Which alteration to the reaction conditions will shift the position of equilibrium to the left?
- Adecreasing the pressure by 100 atm
- Bdecreasing the temperature by $100\,^{\circ}\text{C}$
- Cadding more nitrogen gas to the mixture
- Dremoving the iron catalyst
