If C is the concentration of the diffusing species at distance x from the source and time t, then according to Fick’s second law (assuming diffusion coefficient, D is constant):$ |
| A. | ∂C/∂x = D.(∂C/∂t) |
| B. | ∂C/∂t = D.(∂<sup>2</sup>C/∂x<sup>2</sup>) |
| C. | ∂C/∂x = D.(∂<sup>2</sup>C/∂t<sup>2</sup>) |
| D. | ∂C/∂t = D.(∂C/∂x) |
| Answer» C. ‚Äö√Ñ√∂‚àö‚Ć‚àö√°C/‚Äö√Ñ√∂‚àö‚Ć‚àö√°x = D.(‚Äö√Ñ√∂‚àö‚Ć‚àö√°<sup>2</sup>C/‚Äö√Ñ√∂‚àö‚Ć‚àö√°t<sup>2</sup>) | |
