Can you please draw it for me?how do u put it straight in the conical flask? like u just throw it in there ? this will start the reaction immediately and u still didn't connect ur apparatus to a gas syringe so loss of oxygen (thats an error) and u wont be able to determine the rate if u do it that way. so what the mark scheme is saying is that u separate the peroxide from the catalyst by using a divided flask for example and as soon as u remove the barrier between them u can start ur stop watch and watch ur gas syringe being filled with oxygen!
