How to solve for the equilibrium expression
WebThe equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the K expression, as was illustrated by this previous example.A slightly more challenging example is provided next, in which the reaction … WebOne way to solve this problem is to first find [\text {H}^+] [H+] from the \text {pH} pH: \begin {aligned} [\text {H}_3\text {O}^+]&=10^ {-\text {pH}}\\ \\ &=10^ {-10}\,\text M\\\end {aligned} [H3O+] = 10−pH = 10−10 M We can …
