Chapter 12, Problem 84AE

 (a)

Interpretation Introduction

Interpretation: An explanation as to how the stated conditions help to maximize the yield of ammonia is to be stated.

Concept introduction: The formation or synthesis of ammonia $\left({\text{NH}}_{\text{3}}\right)$ from the reaction between hydrogen and nitrogen gas is an exothermic process that is energy is released during this reaction.

To determine: An explanation as to how “running the reaction at an elevated temperature” helps to maximize the yield of ammonia.

(b)

Interpretation Introduction

Interpretation: An explanation as to how the stated conditions help to maximize the yield of ammonia is to be stated.

Concept introduction: The formation or synthesis of ammonia $\left({\text{NH}}_{\text{3}}\right)$ from the reaction between hydrogen and nitrogen gas is an exothermic process that is energy is released during this reaction.

To determine: An explanation as to how “removing the ammonia from the reaction mixture as it forms” helps to maximize the yield of ammonia.

(c)

Interpretation Introduction

Interpretation: An explanation as to how the stated conditions help to maximize the yield of ammonia is to be stated.

Concept introduction: The formation or synthesis of ammonia $\left({\text{NH}}_{\text{3}}\right)$ from the reaction between hydrogen and nitrogen gas is an exothermic process that is energy is released during this reaction.

To determine: An explanation as to how “using a catalyst” helps to maximize the yield of ammonia.

(d)

Interpretation Introduction

Interpretation: An explanation as to how the stated conditions help to maximize the yield of ammonia is to be stated.

Concept introduction: The formation or synthesis of ammonia $\left({\text{NH}}_{\text{3}}\right)$ from the reaction between hydrogen and nitrogen gas is an exothermic process that is energy is released during this reaction.

To determine: An explanation as to how “running the reaction at high pressure” helps to maximize the yield of ammonia.
