For an elementary reaction 2 ~A + B 3 C rate of appearance of C is 1.3 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ , the rate of disappearance of A is:
Options
- A1.3 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- B2.6 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- C5.2 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹
- D8.66 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
Correct answer
D. 8.66 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹
Step-by-step solution
aligned Rate of reaction & =- 1 2 d [ A ] dt =- d [ B ] dt = 1 3 d [ C ] dt Rate of reaction & = 1 3 d [ C ] dt & = 1 3 1.3 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ & =0.433 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ aligned Rate of disappearance of A aligned & =2 0.433 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ & =0.866 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ & =8.66 10⁻⁵ ~mol ~L ⁻¹ ~s ⁻¹ aligned
