What data points do we combine to make the integrated rate law? a. initial concentration and time b. concentration at some later time, time, and rate constant c. initial concentration, concentration at some later time, and time d. initial concentration, concentration at some later time, time, and rate constant

The correct answer is Option D.

Explanation:

Integrated rate law of the reaction describes the rate of concentration of reactants with respect to time.

For the reaction:

When we start with 'a' moles/liter of A and in time 't', the moles of A reacted are 'x' moles/liters, so the concentration of A after time 't' will be (a - x) moles/liter.

If the reaction is zero order, the integrated rate law will be:

where,

k = rate constant

= Initial concentration of reactant

[A] = concentration of the reactant some time later

t = time

Hence, the correct answer is Option D.
