Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
Compound A is extracted from a solution of A + B into a pure solvent S. A Co-current unit is used for the liquid-liquid extraction. The inlet rate of the solution containing A is 200 moles of B/hr.m2 and the solvent flow, rate is 400 moles of S/m2.hr. The equilibrium data is represented by Y = 3X2, where Y is in moles of a A/moles of B and X is in moles A/moles of S. The maximum percentage extraction achieved in the unit is
For a reaction, the extent of reaction equation is Ni = Nio + ϒVi is Where: Ni = Moles of species I present in the system after the reaction occurs Nio = Moles of species I present in the system when the reaction starts Vi = Stoichiometric coefficient for species i in the specified chemical reaction equation ϒ = Extent of reaction
