The equilibrium constant for the reaction H2O Arrows H OH i
The equilibrium constant for the reaction H2O (Arrows) (H+) + (OH-) is 0.1*10^-14 at 25 degrees C. What is the value of K for the reaction 4H2O (Arrows) 4(H+) + 4(OH-)?
Solution
H2O (l) <---> H+ + OH-
Kw = [H+] [OH-] = 0.1 x 10-14
now
4 H2O (l) <--> 4 H+ + 4OH-
K = [H+]^4 [OH-]^4
K = ( [H+] [OH-])^4
K = ( Kw)^4
K = ( 0.1 x 10-14)^4
K = 1 x 10-60
