Which of the following experimental methods cannot be used to measure the rate of a reaction?
a. measurement of the change in the partial pressure of a gas-phase reactant over time
b. measurement of the equilibrium concentration of an acidic product via titration with a strong base
c. measurement of the absorbance of a colored reactant with time
d. measurement of the absorbance of a colored product with time
e. measurement of the change in the partial pressure of a gas-phase product over time
f. none of the above can be used to measure the rate of the reaction
g. I don't know

The experimental methods which cannot be used to measure the rate of a chemical reaction is: B. measurement of the equilibrium concentration of an acidic product via titration with a strong base.

A chemical reaction can be defined as a chemical process which involves the continuous transformation (rearrangement) of the ionic, atomic or molecular structure of a chemical element by breaking down and forming chemical bonds, so as to produce a new chemical compound.

The rate of a reaction is also known as reaction rate and it refers to the speed at a which the reactants in a chemical reaction are transformed into products. Some of the factors that affect the rate of a reaction are:

Temperature

Catalyst

Concentration of reactants

Pressure

In Chemistry, an experimental method which cannot be used to measure the rate of a chemical reaction is the measurement of the equilibrium concentration of an acidic product by titrating it with a strong base because the concentration of product always remain the same.
