The answer is b, c, d, e

Explanation:

b. 2 N2O5 → 4 NO2 + O2

r = k [N2O5]^2 - -> Second-order regarding global reaction

c. 2 HI → H2 + I2

r = k [HI]^2 - -> Second-order regarding global reaction

d. 2 N2O → 2 N2 + O2

r = k [N2O]^2 - -> Second-order regarding global reaction

e. 2 NO2 → 2 NO + O2

r = k [NO2]^2 - -> Second-order regarding global reaction
