Nitrogen and hydrogen may react to produce ammonia. This reaction is exothermic. The rate and yield of the reaction can be changed by altering the conditions used for the reaction. Which row indicates the effects of adding iron to the mixture and raising the temperature?
- Aadding iron: has no effect on the equilibrium yield; increasing the temperature: reduces the equilibrium yield
- Badding iron: increases the equilibrium yield; increasing the temperature: increases the equilibrium yield
- Cadding iron: increases the equilibrium yield; increasing the temperature: increases the rate
- Dadding iron: increases the rate; increasing the temperature: has no effect on the equilibrium yield
