For the reaction : a A ⟶ b B , it is given that log - d A d t = log d B d t + 0.6020 . What is a : b is?
Options
- A4
- B2
- C1.5
- D0
Correct answer
A. 4
Step-by-step solution
a A ⟶ b B - 1 a dA dt = 1 b dB dt or - d A d t = a b × d b d t log - d A d t = log a b + log d B d t Given : log - d A d t = log d B d t + 0.6020 ∴ log a b = 0.6020 = 2 × 0.3010 = 2 × log 2 = log 4 ∴ a : b = 4
