A person's wound was exposed to some bacteria and then bacteria growth started to happen at the same place. The wound was later treated with some antibacterial medicine and the rate of bacterial decay (r) was found to be proportional with the square of the existing number of bacteria at any instance. Which of the following set of graphs correctly represents the 'before' and 'after' situation of the application of the

Correct answer

1

Step-by-step solution

*Before applying medicine dA dt = K [ A ] (First order growth) (Rate law) A ~A ₀ = N ~N ₀ = e ^ Kt *After applying medicine r =- dA dt = K [ A ]^2 (Rate law) y= Kx ^2 Parabola
