Answer: 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:
[tex]nA\rightarrow Products[/tex]
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:
[tex]k=\frac{1}{t}{[A_0]-[A]}[/tex]
where,
k = rate constant
[tex][A_0][/tex] = Initial concentration of reactant
[A] = concentration of the reactant some time later
t = time
Hence, the correct answer is Option D.
