उत्तर
When dinitrogen is passed over calcium carbide (CaC2) at 1300 K, it reacts with calcium carbide. This reaction produces calcium cyanamide (CaCN2) and carbon. Calcium cyanamide is an important fertilizer.
The reaction is:
\[\ce{N2 + CaC2 -> CaCN2 + C}\]
This process occurs at high temperature (1300 K).
