section 2 gcse additional science aqa isa help chemistry? watch

    • Thread Starter

    im doing my isa section 2 tommorow and from what i know there is a question on context where you have to link your results to your context, trouble is the context doesnt make sense whatsoever.
    so the context is: a company want to attatch posters onto a wall and want to use a catalyst to make the glue set fast but fast enough for them to have enough time to decorate the poster before it is set on.

    so thats the context and i did an experiment with different mases of catalyst ranging from 0.1g to 0.5g, and 0.1 took 90 seconds to stop reacting and 0.5 took 17 seconds to stop reacting. 0.2, 0.3, 0.4 where inbetween and had a trend. so as the mass of catalyst increased the time taken for reaction to stop decreased.

    now how do i link this to the context because it says that it shouldnt make it too fast.
    please help. I would really appreciate it. thanks.

    hey im doing paper 1 of the same isa tomorrow any tips of what is comming up on paper 1? and paper 2 maybey

    what did u write on the plimenary question
