Ammonia is produced in a reversible reaction from hydrogen and nitrogen during the Haber process.
Write the word equation for this reaction.
Which statement is not true about the Haber process for making ammonia?
☐ | A | Platinum is used as a catalyst |
☐ | B | The process is carried out at a temperature of about 450 oC |
☐ | C | The process takes place at a pressure of about 200 atmospheres |
☐ | D | Natural gas is a raw material |
Higher Only
What does the graph show about the effect of pressure and temperature on the Haber process?
☐ | A | Less ammonia is produced at higher pressures |
☐ | B | The yield of ammonia decreases with increased temperature |
☐ | C | The optimum conditions are low pressure and high temperature |
☐ | D | At 500 atmospheres and 400 °C the yield of ammonia is 45% |
Higher Only
Why is a lower temperature than 450 °C not used during the Haber process?
