Hints
Consider the given reaction at equilibrium:
\(\mathrm{N_2(g) +3H_2(g) \rightleftharpoons 2NH_3(g), \Delta H=-Q}\)
Reaction is favoured in forward direction by:
\(\mathrm{N_2(g) +3H_2(g) \rightleftharpoons 2NH_3(g), \Delta H=-Q}\)
Reaction is favoured in forward direction by:
| 1. | Use of catalyst |
| 2. | Decreasing concentration of \(\mathrm{N_2}\) |
| 3. | Low pressure, high temperature and high concentration of ammonia |
| 4. | High pressure, low temperature and higher concentration of \(\mathrm{H_2}\) |
