To attain the straight line by using the calibration curve to show how the cell potential varies with [ Cu 2+ ] and how to obtain the slope of the line should be determined. Concept Introduction : Calibration Curve: It is the method that determines the concentration of substance in unknown sample by comparing with the unknown set of standard samples of known concentrations. Rate of Law : The first order reaction depends on the concentration (C) of only for reactant molecule (A) it is monomolecular reactions. If other reactants must be present, but each will be zero order reaction. First order reaction : The many rate law for a reaction that is first order with respect to a reaction (A) is Reaction rate =k[A] 1 k=Kinetic constant . Rate of reaction : The rate of reactions is an equation that links the reaction rate with the concentrations or pressure of the reactants and constant parameters.

How to measure distance and calculate rate
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
