For an elementary reaction 2 A+3 B 4 C+D the rate of appearance of C at time ' t ' is 2.8 10⁻³ ~mol ~L ⁻¹ ~S ⁻¹ . Rate of disappearance of B at ' t '. t will be
Options
- A4 3 (2.8 10⁻³ ) mol L -1 ~S ⁻¹
- B3 4 (2.8 10⁻³ ) mol L ⁻¹ ~S ⁻¹
- C2 (2.8 10⁻³ ) mol L ⁻¹ ~S ⁻¹
- D1 4 (2.8 10⁻³ ) mol L -1 ~S ⁻¹
Correct answer
B. 3 4 (2.8 10⁻³ ) mol L ⁻¹ ~S ⁻¹
Step-by-step solution
2 A+3 B 4 C+D aligned d(C) d t &=2.8 10⁻³ ~mol ~L ⁻¹ ~s ⁻¹( at time t) - d(B) d t &=? - 1 3 d(B) t &=+ 1 4 d[C] t aligned Rate of disappearance of B= 3 4 rate of appearance of C= 3 4 2.8 10⁻³
