Observe the following reaction 2 A+B C The rate of formation of C is 2.2 10⁻³ ~mol ~L ⁻¹³ ~min ⁻¹ . What is the value of - d[A] d t ( . in . mol L ⁻¹ ⁻¹ ) ?

Options

  1. A2.2 10⁻³
  2. B1.1 10⁻³
  3. C4.4 10⁻³
  4. D5.5 10⁻³

Correct answer

C. 4.4 10⁻³

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 aligned & - d[A] d t =2 d[C] d t & =2 2.2 10⁻³=4.4 10⁻³ ~mol ~L ⁻¹ ~min ⁻¹ aligned
