[问答题]
A student used an online simulativrc9 r-s5.u odon to collecqoo; q qj(w- j75h0l5 btrqv1qt the following data on kinetics of a clock reaction, timing the reaction until a dark blue colour appeared suddenly. They kept all lw7rb-h t;55(qq qqqj0j1 voo 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.
