WebSep 8, 2024 · B Write the equilibrium constant expression for the reaction. Substitute the known K value and the final concentrations to solve for x. C Calculate the final concentration of each substance in the reaction mixture. Check your answers by substituting these values into the equilibrium constant expression to obtain K. Solution: WebThe equilibrium constant expression is now written as follows. Each of these equilibrium constant expressions is the inverse of the other. We can therefore calculate Kc by dividing Kc into 1. We can also calculate equilibrium constants by combining two or more reactions for which the value of Kc is known. reflexive approach anthropology
