TīmeklisIntroduction to Equilibrium. From your earlier experiences in chemistry you have learned to recognize that a chemical reaction can be represented by a chemical equation. A chemical equation contains the chemical formulas of reactants and products separated by an arrow. We then add coefficients to balance the chemical reaction. TīmeklisThe FeNCS2 concentration in Solutions 6-10 was found by using the equation from the calibration curve. Then, the equilibrium constant for each trial was calculated using the equilibrium mole values for the products and reactants. We found the average equilibrium constant of all five solutions was negative which means that the reaction …
