How to solve for the equilibrium expression

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 … 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.
