CHEM 103 Lecture Notes - Lecture 2: Iron(Iii) Nitrate, Potassium Thiocyanate, Thiocyanate
Document Summary
Sample calculations : suppose that we prepare a mixture by mixing 2. 00 10. 2+ ion is formed by the complexation reaction. Its concentration at equilibrium is found to be 2. 50 10. M. our problem is to find kc for the reaction from this information. The initial concentrations of the reactants can be found from the following relation: initial concentration of reactants in mixture. = concentration of stock solution initial concentration of fe. = 0. 00 m, because we did not add any to the mixture. Step 2: fill in the equilibrium concentration of product, fescn. Now you can calculate the equilibrium concentration of product in each of your four trials. Let"s use the fake data: abs of standard = 0. 045. After completing steps 1 and 2, the rice table contains the following information: Step 3: find the change in concentration of each reactant. , must have decreased by the same amount.
