Question:

Nuclear magnetic resonance can be used to determine the mobility of molecules in liquids. A set of measurements on methane in carbon tetrachloride showed that its diffusion coefficient is 2.05 x 10-9m2 S-1 at O°C and 2.89 x 10-9 m2 S-I at 25°C. Deduce what information you can about the mobility of methane in carbon tetrachloride.
