During the phase change from solid ice to liquid water, which bonds/forces are being weakened?
kvasek [131]
INTERmolecular forces (such as dipoles and London dispersion forces).

The actually compound isn't changing (it's still H2O in solid or liquid form), so INTRAmolecular bonds aren't being affected. It's just the strength of attraction between separate molecules that is weakening.

QUESTION 6 Consider the following reaction between the diatomic and monatomic forms of iodine: I2 (g) <-> 2I (g) When 0.09
aalyn [17]

Answer: The equilibrium constant is 3.3\times 10^{-4}

Explanation:

Initial concentration of I_2 = 0.095 M  

The given balanced equilibrium reaction is,

                            I_2(g)\rightleftharpoons 2I(g)

Initial conc.          0.095 M       0 M

At eqm. conc.     (0.095-x) M   (2x) M

Given : 2x = 0.0055

x = 0.00275

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[l]^2}{[I_2]}  

Now put all the given values in this expression, we get :

K_c=\frac{(0.0055)^2}{(0.095-0.00275)}

K_c=\frac{(0.0055)^2}{0.09225}=0.00033

Thus the equilibrium constant is 3.3\times 10^{-4}
