Observe the following reaction 2 A+B C The rate of formation of C is 2.2 10⁻³ ~mol L ⁻¹ ⁻¹ . What is the value of - d[A] d t (in mol . L ⁻¹ ⁻¹ ) ?
Options
- A2.2 10⁻³
- B1.1 10⁻³
- C4.4 10⁻³
- D5.5 10⁻³
Correct answer
C. 4.4 10⁻³
Step-by-step solution
2 A+B C rate of reaction aligned & =- 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 ~mol ~L ⁻¹ ~min ⁻¹ aligned
