    Not sure if i'm doing these Q's right, I was away for the lesson so have no idea if there right! One of the Q's is:

    Stoichiometric equation: 2A + B --> D

    Mechanism: A + B --> X slow
    A + X --> D fast

    Therefore what is the rate equation? Is it: Rate = k [B]

    Yup!

    Although, is there any other info eg. graphs?

    no ... rate equation must involve everything that appears up to and including the slowest step.

    so in this case, the slow step involves one A and one B, so the rate equation is
    Rate = k[A][B]
