For the preceding question, which of the following equations best represents the reaction?

a. 6N2 + 6H2 ⟶ 4NH3+ 4N2

b. N2 + H2 ⟶ NH3

c. N + 3H ⟶ NH3

d. N2 + 3H2 ⟶ 2NH3

e. 2N2 + 6H2 ⟶ 4NH3

Justify your choice, and for choices you did not pick, explain what is wrong with them.

Interpretation Introduction

Interpretation: From the given options, the reaction that best represents a chemical equation is to be identified.

Concept introduction: According to the law of conservation of mass, the mass of the substances that take part in a chemical reaction remains conserved. Therefore, the mass of elements on the reactant side is equal to their mass on the product side.

To Identify: The reaction that best represents a chemical equation, from the given list.

General Info: Coefficients are added to the reactants and products to obtain their equal masses on both, the reactant side and the product side.

Explanation of Solution

  1. a. The given reaction is not appropriate. The number of unreacted molecules is not necessary to be mentioned. The four unreacted nitrogen molecules mentioned on the product side are not necessary to be stated.
  1. b. The given reaction is not appropriate. The equation is not balanced and hence does not follow the law of conservation of mass.
  1. c...
