Rate = k [BrO₂]ᵐ [OH⁻]ⁿ
Expt. No. 1: 0.0248 = k (0.060)ᵐ (0.030)ⁿ …… [1]
Expt. No. 2: 0.00276 = k (0.020)ᵐ (0.030)ⁿ …… [2]
[1]/[2]:
9 = 3ᵐ
3ᵐ = 3²
Order respect to BrO₂, m = 2
The answer: 2
(The 1st option)
====
OR:
Compare 1 and 2:
When [BrO₂] becomes 1/3, the reate becomes (1/9) = (1/3)²
Order respect to BrO₂ = 2
The answer: 2
