[问答题]
A student used an online simulation to collect the followi3vherrf d(o/sv+ /l4hng data on kineticsq di (s+yq3l)7xjjrr* of a clock reaction, timing s jj)xdr il q*3y7(rq+the reaction until a dark blue colour appeared suddenly. They kept all other factors constant, including the concentrations of the other reactants$([H_2SO_4]=0.10mol dm^{-3},[Na_2S_2O_3]=0.030mol dm^{-3},[starh]=0.001mol dm^{-3})$

Trial	$[H_2O_2]$, $mol$$dm^{-3}$	$[KI]$, $mol$$dm^{-3}$	$Reaction Time (s)$	$Rate of Reaction$
1	0.045	0.100	3.59
2	0.045	0.050	7.20
3	0.045	0.025	14.00
4	0.0225	0.100	7.05

1.Fill in the table with the respective rate of reaction for each trial.
2.Sketch the graph for rate vs [KI] and state the order of reaction with respect to KI.
3.Determine the order of reaction with respect to hydrogen peroxide using the data table.
4.Suggest two further experiments that could be done to determine the rate expression.
5.Suggest an advantage or a disadvantage about using a simulation to collect data.
