Chemical Equilibrium 0.0 / 5 ? Chemistryequilibrium, constant, dispersion,UniversityAll boards Created by: Broken RoseCreated on: 13-12-14 14:41 If K=1 then The conc of reactants and products are similar and reaction maybe typically reversible 1 of 12 The difference between the equlibrium constant and the reaction quotient? Reaction quoitient uses actual concs (That maybe initial) 2 of 12 When th reaction Quotient and rate constant is compared it is used to determine? The direction of the reaction 3 of 12 Equilibrium in live systems. Which is incorrect None 4 of 12 Dispersion systems. Which is Incorrect? 2 types: Homogenous (eg emulsion, suspension foam) and heterogenous (eg. solution, mixtures of gases, alloys) 5 of 12 What is a reverse osmosis? Filtration of solution using external pressure through semipermeable membrane which can retain solute so a pure solution can be obtained 6 of 12 Calculate osmatic pressure=RTc. Which is incorrect? c= osmolality 7 of 12 Differences between osmolarity and osmolaity? Osmolarity = mol/kg 8 of 12 What is oncotic pressure? Colloid osmotic pressure (osmotic pressure of a colloid solution eg. cytosol, blood plasma) 9 of 12 How to calculate the activity of particle (B)? aB =YB(activity coefficient) x ConcB 10 of 12 What is the equation for ionic strenght? I= 0.5 (sum of the conc of ions and (charge of ions)^2) 11 of 12 What does the increasing ionic strenght mean? This decreases the activity coefficient and increases the difference between activity and conc (a 12 of 12
