Calculating Reaction Order with an Excess of One Reactant
A+B -> C+D The complete data is as follows: The initial concentration of A is 400 mmol/L and initial concentration of B is 0.4 mmol/L. The following data is for concentration of C in mmol/L at different times T in seconds T sec: 0 120 240 360 Infinity [C] : 0 0.2 0.3 0.35 0.4 Assuming ...continues
Standard Electrode Potentials and Gibbs Free Energy
1. What is the standard electrode potential for the half reaction in which free ferric ion is reduced to elemental Iron? 2. Place the following chemical species in ascending order (in energetic terms) as electron acceptors under standard conditions. Fe3+ (reduced to Fe2+); Zn2+ (reduced to Zn); H+;Ag+;Cu2+ (reduced to Cu+) ...continues
Free Energies of Reaction from Reduction Potentials: Oxidation of Lactate with Fe3+ (ferric ion).
a)Under standard conditions , will the oxidation of lactate using Fe3+ as electron acceptor prove energetically favorable? What is the change in free energy associated with the complete oxidation of lactate to carbon dioxide by Fe3+? (Assume reduction of Fe3+ to Fe2+) Given information pe0=-0.68 (My knowledge about this is: p ...continues
Prediction of Changes to DeltaG in a Non-Standard Cell
-438 kJ/mol is the free energy change of lactate oxidation by Fe3+ under non-standard conditions assuming that: C3H5O3- + 12 Fe3+ + 3 H2O -----> 3 CO2 + 11 H+ + 12 Fe2+ [Fe2+]=10^-4 M pH=7 T=25 degree centigrade [lactate]=10^-3 M Carbon dioxide is in equilibrium with atmospheric CO2 Fe3+ is in equilibrium with ...continues

Can you explain zeta potential in simple terms? If you haven't deduced by now, my study mates and I are all Chem Engineering grads from the early 80's and sadly have forgotten much of what we academically one knew....we are all now pursuing Master's degrees and it is a struggle re-learning much of this material. Also...we ...continues
If you have an electrolyte solution in which you have inserted an electrode to charge it either positive or negative - and then you remove the electrode - is it possible to then magnetize this solution by any one or several methods?
Conductivity of acetic acid KCl solutions
The conductivity of a 0.1 moldm^-3 solution of potassium chloride at298K was found to be 1.1639 x 10^-2 Scm^-1. In a separate experiment at 298K the resistance of a 0.1 moldm^-3 solution of ethanoic acid was determined as 300 ohms and the resistance of the potassium chloride solution was fond to be 33.21 ohms. Given that the spe ...continues
