    (a) backward direction

    (b) forward direction

    (c) no change

    Explanation:

    (a)

    On increasing the concentration of NO, the reaction will go in backward direction, as, according to le chatelier's principle,

    In a chemical equilibrium, when the concentration, pressure or temperature is changed, the equilibrium of the reaction is disturbed, hence, in order to gain attain the equilibrium the reaction moves in order to counteract the changes.

    So, in this case, the reaction goes back, to reduce the increased concentration of NO.

    (b)

    On increasing the concentration of NO2, the reaction goes in forward direction,

    according to le chatelier's principle,

    the reaction moves in forward direction, to reduce the increased concentration of NO2.

    (c)

    No change,

    As, changing the volume, does not effect change in the concentration,

    Hence,

    No change, as the system is allowed to expand to 5 times its initial value.
