The Haber process is used to make ammonia at a temperature of 400 °C and a pressure of 20 000 kPa. The temperature is changed to 500 °C but the pressure is kept the same. What will be the effects of this change on the production of ammonia?

1. AIt is made at an increased rate and the position of the equilibrium moves to the left.
2. BIt is made at an increased rate and the position of the equilibrium moves to the right.
3. CIt is made at a decreased rate and the position of the equilibrium moves to the left.
4. DIt is made at a decreased rate and the position of the equilibrium moves to the right.
