The lattice energy is the amount of energy released when the ions that make up a crystal lattice are brought together. Now, this energy is dependent on the charge concentration of these ions. Both potassium and rubidium form ions with a +1 charge, while bromine and iodine form ions with -1 charge. However, because potassium and bromine are smaller than rubidium and iodine respectively, the charge is more concentrated. Therefore, more energy is released when potassium and bromine are brought together.
The experimental method for measuring the change in concentration with time for the given reaction is by measuring the amount of gas a reaction releases over time.
2NO(g) + Cl₂(g) → 2NOCl(g)
<h3>What is reaction rate?</h3>
- The reaction rate is the rate at which a chemical reaction proceeds.
- Which is proportional to both the increase in a product's concentration per unit time and the decrease in a reactant's concentration per unit time.
- There is a wide range in reaction times.
- The general definition is that the term "rate of a reaction" refers to the pace at which a reaction occurs.
- As an illustration, iron rusting has a low reaction rate since the process is slow but wood burning has a high reaction rate because the process is quick.
