    Do not they specify weither it is a composition or decomposition reaction?

    @rvc, the trick was that they wanted you to consider when changes like pressure, temperature and concentration of substances is involved. As this happens, the system shifts as to oppose such changes, but at the mean time, they are not always equal. That is why is more general to say that the reactions continue to occur.

    You think C. The forward reaction is spontaneous and the reverse reaction is non spontaneous?

    Haha, the way you asked is as if my answer is wrong. Hehe, that is what I believe. For me, otherwise is the other way round, because I confiund that at times.

    Rate means something over time. It will be equilibrium.
