    here each reactant is first order.. so if we double the conc of each one alone the rate will also be doubled and if we double the concen of both together the rate will be x4 .. so in part B why is D the incorrect one , it makes sense :bawling:

    Iodine isn't in the rate equation, so doubling its concentration wouldn't affect the rate of reaction.
