Which of the following statements is false for the chemical equation given below? Assume the reaction goes to completion. N_2+3 H_2→2 〖NH〗_3 The reaction of 1 mole of H2 will produce 2/3 mole of NH3 1 mole of N2 will produce 2 moles of NH3 1 molecule of nitrogen requires 3 molecules of hydrogen for a complete reaction The reaction of 14 g of N2 produces 17 g of NH3 The reaction of 3 moles of H2 gas will produce 17 g of NH3

Answer: The following statement is false:

1. The reaction of 3 moles of H2 gas will produce 17 g of NH3

Explanation: From the equation of the reaction, 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of Ammonia.

Statement 1 is correct because the ratio of NH3 to H2 is 2/3; i. e. for every molecule of H2 reacting, 2/3 moles of NH3 is produced.

Statement 2 is correct because from the equation of reaction, 1 mole of N2 reacts to produce 2 moles of NH3.

Statement 3 is correct because from the equation of reaction, 1 mole of nitrogen (N2) requires 3 molecules of hydrogen for a complete reaction.

Statement 4 is correct because from the equation of reaction, 1 mole of nitrogen, N2 (mass=28g) produces 2 moles of ammonia, NH3 (mass=34g). Therefore, in a simpler ratio, The reaction of 14 g of N2 produces 17 g of NH3

Statement 5 is false because, from the equation of reaction, 3 moles of H2 will produce 2 moles of NH3 (mass = 34g) and not 17g of NH3.

The reaction of 3 moles of hydrogen does not give 17g of ammonia

Explanation:

From the balanced reaction equation, 3 moles of hydrogen gas yields 34g of ammonia. Only 1.5 moles of hydrogen gas can yield 17g of ammonia.
