Options
- A2.303 5.48 10⁻¹⁴ 3
- B2.303 5.48 10⁻¹⁴ 2
- C2.303 5.48 10⁻¹⁴ 1 3
- D2.303 5.48 10⁻¹⁴ 2 3
Correct answer
A. 2.303 5.48 10⁻¹⁴ 3
Step-by-step solution
For two third of a reaction aligned [A]₀=a₁[A] & =a- 2 3 a= a 3 t_ 2 / 3 & = 2.303 k [A]₀ [A] & = 2.303 5.48 10⁻¹⁴ a a / 3 & = 2.303 5.48 10⁻¹⁴ 3 aligned
