Question #68286
A dimer, X, is stable when solid but a dynamic equilibrium is set up in solution.
X(aq) 2Y(aq)
A solution of X has an initial concentration of 0.50 mol dm–3. When equilibrium has been reached
[X(aq)] has fallen to 0.25moldm–3.
The changes in [X(aq)] and [Y(aq)] are plotted against time until equilibrium is reached. The value
of Kc is then calculated.
Which graph and value for Kc are correct?

No plots for Kc were provided, so we can only say how it should look like
Why is this the answer how do we get the Kc
