Question

The rate of the reaction:   NO₂(g) + CO(g) → NO(g) + CO₂(g)   was determined in three experiments at 225°C. The results are given in the following table:

Experiment	NO2(M)	CO (M)	Initial Rate –ΔNO2/Δt (M/s)
1	0.277	0.898	0.19
2	0.277	0.449	0.19
3	0.462	0.449	0.576

Calculate the value of the rate constant at 225°C using reaction 1 data
