Ammonia is produced using the Haber process. This reaction is exothermic. $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g) \qquad \Delta H = -92\,\text{kJ mol}^{-1}$ Which statement concerning the Haber process is correct?
- AThe reaction is irreversible and produces only one product.
- BThe reaction is reversible and produces less ammonia at high pressure.
- CThe reaction is reversible and produces less ammonia at high temperature.
- DThe reaction is slow because a catalyst is not used in the Haber process.
