Which of the following equation is related to Fick’s second law_________

Which of the following equation is related to Fick’s second law_________ Correct Answer (∂C/∂X) = D*(∂2C/∂X2)

These equations relate the rate of change of composition with time to the concentration profile C(x). Equation has a simple graphical interpretation as (∂2C/∂X2) is the curvature of the C versus x curve.
