What is the correct symbol equation for the Haber process?

The correct symbol equation for the Haber process is represented by the reaction of nitrogen and hydrogen gases to produce ammonia, which is essential for creating fertilizers. The accurate representation shows the balanced equation: nitrogen (N2) reacts with three molecules of hydrogen (H2) to yield two molecules of ammonia (NH3).

This equation demonstrates the conservation of mass, ensuring that the number of atoms on both sides is equal; one molecule of nitrogen contains two nitrogen atoms, and three molecules of hydrogen contain six hydrogen atoms. On the product side, two molecules of ammonia consist of two nitrogen atoms and six hydrogen atoms, perfectly balancing the equation.

In the other choices, the incorrect equations either misrepresent the stoichiometry or do not adhere to the conservation of atoms. For instance, some options might show an incorrect number of hydrogen atoms or present an incorrect product. The balanced equation is crucial to understanding the efficiency of the process, which operates under high temperature and pressure to optimize ammonia production.
