What is the rate of disappearance of B in following reaction? 2 ~A + B 3 C , if rate of appearance of C is 1.3 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ .
Options
- A4.33 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
- B8.6 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
- C2.6 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- D5.2 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
Correct answer
A. 4.33 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
Step-by-step solution
Rate of disappearance of B 1 = Rate of appearance of C 3 Rate of disappearance of B = 1 3 1.3 10⁻⁴=4.33 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
