    MATLAB Chromatography PDE MOL

    Hello all I am using the method of lines to solve the following PDE: ## \frac {\partial C} {\partial t} + F\frac {\partial q} {\partial t} + u \frac {dC} {dz} = D_{ax} \frac{\partial^2 C} {\partial z^2} ## ## \frac {\partial q} {\partial t} = k (q^{*}-q) ## With these initial conditions: ##...

    Latent Heat and Bond Energy

    The kinetic theory says that temperature is the measure of the average kinetic energy. That would mean then : The temperature rises with the rise in kinetic energy. We know that when matter changes state 'latent heat' helps in 'breaking the bonds' at the transition phase and that this 'extra...

    Chromatography: The difference in kinetic energy

    In chromatography, the upper portion of the moving water solvent has more kinetic energy, than the lower portion of the moving water solvent because the lower portion of water molecules have to face more obstacles in the way because of the absorbed water molecules. Is it true?

    Should carbon boiling stones be used in O-chem reactions?

    I performed column cromatography on an oil, and used carbon boiling chips but got some weird IR. I used hexanes and acetone as solvents, im trying to figure out some of the spikes, soo im thinking that maybe the boiling stone being carbon could acted as activated carbon and absorbed some organic...

    Separation Through chromatography

    Dear all, We all know that chromatography is a separation technique. In paper or TLC,the mixture is differentiated according to their relative affinities with the solvent on the paper or glass plate. How do we really separate the mixture. Kindly, help me how to extract the components...
