NEETChemistryChemical KineticsMCQ+4 / −1
The rate constant of the reaction A →\to→ B is 0.6 ×\times× 10−-−3 mol L−-−1 s−-−1. If the concentration of A is 5 M, then concentration of B after 20 minutes is
  1. A
    3.60 M
  2. B
    0.36 M
  3. C
    0.72 M
  4. D
    1.08 M

Correct answer: C

For zero order reaction unit of rate constant is mole per second.

∴\therefore∴ For zero order

x = kt

⇒\Rightarrow⇒ x = 0.6 × 10–3 × 20 × 60 = 0.72 M
