The concentration of a solute is very important in studying chemical reactions because it determines how often molecules collide in solution and thus indirectly determines the rates of reactions and the conditions at equilibrium (see chemical equilibrium)....
When the system reaches equilibrium, what is the molar concentration of hydrogen ions (H3O+)? What is the acid ionization constant for an acid with a pH of 2.11 and an equilibrium concentration of 0.30 M? Assume the pH of your deionized water solution is 7. Then ...
FORMULA: n M = V = 5.0 mol 1.25 M V = 4.00 L DIMENSIONAL ANALYSIS: This is not a gas at STP, so can’t use 22.4L/mol. Concentration is used as the conversion factor between moles and litres in solutions. 5.0 mol 1 L 4.00 L = 1.25 mol n n = (0.4)(0.225) M = V = = 0...
Recently, the GK theory of thermal transport has been combined with state-of-the art quantum simulation methods based on density-functional theory (DFT)17,19,20 and successfully employed to evaluate κ from equilibrium molecular dynamics (MD) simulations of superionic systems, even at extreme ...
