Answer:
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

Explanation:
Answer:
4.49dm3
Explanation:
2NH4Cl + Ca(OH)2 —> CaCl2 + 2NH3 + 2H2O
First, we need to convert 10g of ammonium chloride to mole. This is illustrated below:
Molar Mass of NH4Cl = 14 + (4x1) + 35.5 = 53.5g/mol
Mass of NH4Cl = 10g
Number of mole = Mass /Molar Mass
Number of mole of NH4Cl = 10/53.5 = 0.187mol
From the equation,
2moles of NH4Cl produced 2 moles of NH3.
Therefore, 0.187mol of NH4Cl will also produce 0.187mol of NH3
Now we can obtain the volume of NH3 produced by doing the following:
1mole of any gas occupy 24dm3
Therefore, 0.187mol of NH3 will occupy = 0.187 x 24 = 4.49dm3
