Question

The rate expression for the reaction between H2O2 and KI is:
rate = k[H2O2]
m [KI]n
where: k = rate constant
m = order of reaction with respect to H2O2
n = order of reaction with respect to KI

Table 2: Molarity of H₂O₂ and KI and Reaction Rate

Trial	H₂O₂Concentration, M	KI Concentration, M	Reaction Rate (Reciprocal Slope)
1	0.29 M	0.40 M	14.08
2	0.29 M	0.20M	25
3	_{0.023 M}	0.40 M	20

please help me with this part and please show me all steps
