The rate of flow of a liquid through a capillary tube of length $$L$$ and radius $$r$$ under a pressure difference $$p$$ is given by the poiseuille's formula $$V = \pi \,p\,{r^4}/8\eta L$$. Determine the dimensions of the coefficient of viscosity $$\eta $$ of the liquid.

View Answer$$'A'$$ is optically active (dextro-rototory) while $$'B'$$ and $$'C'$$ are optically inactive but $$'B'$$ takes part in a titration reaction (fast reaction) with $$H_{2}O_{2}$$. Hence, the progress of reaction can be monitored by measuring rotation of plane polarised light or by measuring volume of $$H_{2}O_{2}$$ consumed in titration.
In an experiment the optical rotation was found to be $$\theta = 40^{\circ}$$ at $$t = 20\ min$$ and $$\theta = 10^{\circ}$$ at $$t = 50\ min$$. from start of the reaction. If the progress would have been monitored by titration method, volume of $$H_{2}O_{2}$$ consumed at $$t = 15\ min$$. (from start) is $$40\ ml$$ then volume of $$H_{2}O_{2}$$ consumed at $$t = 60$$ min will be:
- A. $$60\ ml$$
- B. $$75\ ml$$
- C. $$52.5\ ml$$
- D. $$90\ ml$$
