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

The Reaction Rate for a given chemical reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time.

The following are used to measure the change in concentration of the reactants or the change in concentration of the products per unit time.

1) measurement of the change in the partial pressure of a gas-phase reactant over time

2) measurement of the absorbance of a colored reactant with time

An Acid base titration on the other hand is defined as

An acid–base titration is the determination of the concentration of an acid or base by exactly neutralizing the acid or base with an acid or base of known concentration. This allows for quantitative analysis of the concentration of an unknown acid or base solution.

In this there is no time component of chnage in concentration with time

Therefore measurement of the equilibrium concentration of an acidic product via titration with a strong base cannot be used to measure the rate of a reaction
