Observe the following reaction, 2 A + B → C The rate of formation of C is 2.2 × 10 - 3 mol L -1 mtextn -1 , then rate of disappearance of A is

Options

  1. A2.2 × 10 - 3 mol L -1 min -1
  2. B1.1 × 10 - 3 mol L -1 min -1
  3. C4.4 × 10 - 3 mol L -1 min -1
  4. D5.5 × 10 - 3 mol L -1 min -1

Correct answer

C. 4.4 × 10 - 3 mol L -1 min -1

Step-by-step solution

2 A + B → C Rate of reaction, = - 1 2 d A d t = - d B d t = d C d t ∴ - d A d t = 2 d [ C ] d t = 2 × 2.2 × 10 - 3 = 4.4 × 10 - 3 m o l L - 1 m i n - 1
