    Gases A and B react as shown in the following equation.
    2A(g) + B(g) -------->C(g) + D(g)
    The initial rate of the reaction was measured in a series of experiments at a constant
    temperature. The following rate equation was determined.
    rate = k[A]2


    The reaction is zero order with respect to B.
    State the significance of this zero order for the mechanism of the reaction.

    this is one mark question but I was confused can someone explain that to me.

    Simply I am thinking that B is not only involved in the rate-determining step so it has not directly effect on the rate because required for the reaction to proceed....

    B is not in the rate-determining step.
    That is all you need put for 1 mark.
