Biotransformation of an organic compound having concentration (x) can be modeled using an ordinary differential equation (dx /dt )+ kx2 =  0, where k is the reaction rate constant. If x = a at t = 0, the solution of the equation is

1.  x = ae-kt

2.  1/x = (1/a)+ kt

3.  x = a (1-e-kt)

4.  x = a + kt

View Answer
