1 1/3 = 4/3 (because (3 * 1 + 1) / 3)

We need both parts of sum to have common denominator.
Second part have denominator = 6.
When we multiply nominator and denominator of first part by 2 we get 8/6 (what is legit operation on fractions)

Now easily add:
8/6 + (- 5/6) = 8/6 - 5/6 = 3/6 (here we can divide both nominator and denominator by 3 to get "nicer" result) = 1/2

Based on a kc value of 0.200 and the given data table, what are the equilibrium concentrations of xy, x, and y, respectively?
MariettaO [177]
There is no given data table but based on the question, the reaction is
xy <=> x + y
If we let M as the initial concentration of xy and c as the in the concentration after the dissociation, then we can use the ICE method
    xy   <=>   x    +   y
I    M
C  -c            c         c
-----------------------------
E  M-c          c         c

Solve for c using
Kc = c(c) / (M - c)
And the concentration of the xy, x, and y can then be determined
