Chapter 6: Q38P (page 143)

The equilibrium constant for the reaction $H_{2} O 鈬� H^{+} + O H^{-}$ is $1.0 脳 10^{- 14}$ at $25 掳 C$ . What is the value of K for the reaction $4 H_{2} O 鈬� 4 H^{+} + 4 O H^{-}$ ?

Short Answer

Expert verified

The value of the equilibrium constant is $1.0 脳 10^{- 56}$

Step by step solution

Definition of Equilibrium constant

In the equilibrium reaction, the equilibrium constant is given as the ratio of the concentration of the products to the concentration of the reactant.

The formula of the ionic product of water is:

$K_{W} = [H^{+}] [O H]$

Calculate the value of equilibrium constant

For the given reaction:

$4 H_{2} O 鈬� 4 H^{+} + 4 O H^{-}$

The equilibrium concentration is given by:

$K = \frac{[H^{+}] {[O H^{-}]}^{4}}{{[H_{2} O]}^{4}}$

Since undissociated water molecules are present in large concentrations, we can write:

role="math" localid="1663326848932" $K = {[H^{+}]}^{4} {[O H^{-}]}^{4} = {([H^{+}] [O H^{-}])}^{4} = {(K_{W})}^{4} = 1.0 脳 10^{- 56}$
