The number of particles given by n = – D\(\frac{n_{2}-n_{1}}{x_{2}-x_{1}}\) are crossing a unit area perpendicular to x–axis in unit time, where n1 and n2 are the number of particles per unit volume for the values x1 and x2 of x respectively. Then the dimensional formula of diffusion constant D is
- [M0LT0]
- [M0L2T–4]
- [M0LT–3]
- [M0L2T–1]
Answer
(D) [M 0 L 2 T –1 ]
