    You are right! It was asking about hydrogen iodide which was the reactant, so yh the yield of that would decrease if temp was raised
    Yeh less hydrogen iodide, more hydrogen and iodine as forward reaction is endothermic

    I think for C3 it may be lower because it was quite a difficult paper
