Consider the following mechanism for the reaction of hydrogen and iodine monochloride: Step 1. H21g2 + ICl1g2S HI1g2 + HCl1g2 Step 2. HI1g2 + ICl1g2S I21g2 + HCl1g2 (b) Identify any reaction intermediates.

Verified step by step guidance

1. Identify the overall reaction by adding the two elementary steps together.
2. Cancel out any species that appear on both sides of the reaction equation.
3. Recognize that intermediates are species that are produced in one step and consumed in a subsequent step.
4. Look for species that are not present in the overall reaction but appear in the mechanism steps.
5. Identify the intermediate(s) based on the above analysis.

Key Concepts

Reaction Intermediates

Reaction intermediates are species that are formed during the course of a chemical reaction but are not present in the final products. They exist only transiently and are typically consumed in subsequent steps of the reaction mechanism. In the given mechanism, identifying these intermediates is crucial for understanding the overall reaction pathway.

Chemical Reaction Mechanism

A chemical reaction mechanism is a step-by-step description of the process by which reactants are converted into products. It outlines the individual steps, including the formation and consumption of intermediates, and provides insight into the reaction's kinetics and dynamics. Understanding the mechanism helps in predicting the behavior of the reaction under various conditions.

Stoichiometry

Stoichiometry involves the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It allows chemists to determine the proportions of substances involved and predict the amounts of products formed from given quantities of reactants. In the context of the provided mechanism, stoichiometry helps in understanding the relationships between the intermediates and the final products.
