All steps before the slow step should be taken into account, but any steps listed after should not be accounted for

Re: Negative 1/a

Because the reactant is being consumed, the overall concentration of the reactant is decreasing so there is a negative rate of change. However, if the question asked at what rate was A being consumed, then it will be a positive answer. Just be careful about how the question is worded! Can you pleas...
