The concentration C (mole/ m3 ) for a specific problem depends

The concentration C (mole/ m3 ) for a specific problem depends on position z and time t, and it is given by the following equation; C()=0es2ds The transformation variable is =2Dtz. D is the diffusion coefficient, and it has a value of 7106cm2/s. 1. What is ddC ? 2. If the flux is J=DzC, what are the S.I. units of flux ? 3. For the given data, what is the flux at z=0 ? 4. What is the flux at z=0.1m ? 5. If the flux occurs across a cross-sectional area of A=2m2, then the total molar flow rate is JA. What is the total molar flow rate at z=0.1m ? 6. What is the total number of moles that has passed through the cross-sectional area at z=0m over a one hour period
