Chapter 12, Problem 12.92SP

(a)

Interpretation Introduction

Interpretation:

For the thermal decomposition reaction of nitryl chloride, the overall reaction has to be given.

(b)

Interpretation Introduction

Interpretation:

For the thermal decomposition reaction of nitryl chloride, the molecularity of each elementary reaction has to be given.

Concept introduction:

Molecularity of reaction:

Unimolecular: A molecule (reactant) undergoes rearrangement itself to give one or more products is said to be unimolecuar reactions.

Bimolecular: Two molecules (reactants) undergo collisions to give one or more products is said to be bimolecular reactions.

Termolecular: Three molecules undergo collision to give one or more products is said to be termolecular reactions.

(c)

Interpretation Introduction

Interpretation:

For the thermal decomposition reaction of nitryl chloride, the rate law has to be given.

Concept introduction:

Rate law of a reaction:

It is an equation that related to the dependence of the reaction rate on the concentration of each substrates (reactants).
