Q16.18P - Chemistry: Molecular Nature Of Matter And Change

Question

Reaction rate is expressed in terms of changes in the concentration of reactants and products. Write a balanced equation for

Rate$\mathbf{=}\mathbf{-}\frac{\mathbf{1}}{\mathbf{2}}$$\frac{\mathbf{∆}\mathbf{\left[}{\mathbf{N}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{5}}\mathbf{\right]}}{\mathbf{∆}\mathbf{t}}\mathbf{=}\frac{\mathbf{1}}{\mathbf{4}}\frac{\mathbf{∆}\mathbf{\left[}{\mathbf{NO}}_{\mathbf{2}}\mathbf{\right]}}{\mathbf{∆}\mathbf{t}}\mathbf{=}\frac{\mathbf{∆}\mathbf{\left[}{\mathbf{O}}_{\mathbf{2}}\mathbf{\right]}}{\mathbf{∆}\mathbf{t}}$

Step-by-Step Solution

Answer

The balanced equation is as follows:

$2{\mathrm{N}}_2{\mathrm{O}}_{5\left(\mathrm{g}\right)}\to 4{\mathrm{NO}}_{2\left(\mathrm{g}\right)+ }{\mathrm{O}}_{2\left(\mathrm{g}\right)}$

What is the reaction rate?

The rate of reaction, also known as the reaction rate, is the rate at which reactants become products. The pace at which a response occurs is an excellent diagnostic tool. We can create strategies to optimize production by learning how quickly items are made and what causes responses to slow down. This data is required for the large-scale production of various chemicals, including fertilizers, medicines, and home cleaning products.

Balanced equation

The word in the rate equation with a negative sign denotes reactant, whereas the term with a positive sign denotes product. The inverse of the fraction yields the molecules' stoichiometric coefficients. Write a balanced equation as follows:

$2{\mathrm{N}}_2{\mathrm{O}}_{5\left(\mathrm{g}\right)}\to 4{\mathrm{NO}}_{2\left(\mathrm{g}\right)+ }{\mathrm{O}}_{2\left(\mathrm{g}\right)}$
