Chapter 16: Q16.18 P (page 729)

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

Rate=鈭�12螖[N2O5]螖t=14螖[NO2]螖t=螖[O2]螖t

Short Answer

Expert verified

The balanced equation is as follows:

2N2O5(g)鈫�4NO2(g)+O2(g)

Step by step solution

01

Step 1: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.

02

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:

2N2O5(g)鈫�4NO2(g)+O2(g)

Most popular questions from this chapter

( a) For a reaction with a given Ea, how does an increase in T affect the rate?

(b) For a reaction at a given T, how does a decrease in Ea affect the rate?

The rate law for the general reaction

aA+bB+...鈫�cC+dD+...

is rate =k[A]m[B]n...

(a) Explain the meaning of k.

(b) Explain the meanings of m and n. Does m a and n b? Explain.

(c) If the reaction is first order in A and second order in B, and time is measured in minutes (min), what are the units for k?

Give the individual reaction orders for all substances and the overall reaction order from the following rate law:

Rate=k[BrO3-][Br-][H+]2

Suggest an experimental method for measuring the change in concentration with time for each of the following reactions:
(a)CH3CH2Br(l)+H2O(l)鈫�CH3CH2OH(l)+HBr(aq)(b)2NO(g)+Cl2(g)鈫�2NOCl(g)

While developing a catalytic process to make ethylene glycol from synthesis gas CO+H2 , a chemical engineer finds the rate is fourth-order in gas pressure. The uncertainty in the pressure reading is 5%. When the catalyst is modified, the rate increases by 10%. If you were the company patent attorney, would you file for a patent on this catalyst modification? Explain.
