Answer: The expression of [tex]K_b[/tex] is written below.
Explanation:
We are given a chemical compound which is trimethylamine that acts as a weak base when dissolved in water.
It accepts a proton from the water to form trimethylammonium ion and hydroxide ion.
The chemical equation for the reaction of trimethylamine in water follows:
[tex](CH_3)_3N+H_2O\rightleftharpoons (CH_3)_3NH^++OH^-[/tex]
The expression of [tex]K_b[/tex] for above equation follows:
[tex]K_b=\frac{[(CH_3)_3NH^+][OH^-]}{[(CH_3)_3N]}[/tex]
Hence, the expression of [tex]K_b[/tex] is written above.
