What type of reaction is the equation N2(g) + 3H2(g) -> 2NH3(g) classified as?

What type of reaction is the equation N2(g) + 3H2(g) -> 2NH3(g) classified as?

• A. Decomposition
• B. Single Substitution
• C. Combination
• D. Double Substitution

Answer: (C)

The reaction represented by the equation N2(g) + 3H2(g) -> 2NH3(g) is classified as a combination reaction. In a combination reaction, two or more reactants combine to form a single product. In this specific case, nitrogen gas (N2) and hydrogen gas (H2) combine to form ammonia (NH3). The essential characteristic that defines a combination reaction is the formation of one product from two or more reactants, which is exactly what occurs here. The reactants N2 and H2 are in their elemental forms, and when they react, they produce ammonia as the sole product. Understanding this type of reaction is important in various applications, including industrial processes like the Haber process for synthesizing ammonia from nitrogen and hydrogen gas.
