The rate law for the reaction A + B C at 25^ C is given by rate =k[A][B]^2 . Calculate the rate of reaction if rate constant at same temperature is 6.25 ~mol ⁻² dm ^6 ~s ⁻¹[[ ~A ]=1 M ,[ B ]=0.2 M ]
Options
- A0.25 ~mol dm ⁻³ ~s ⁻¹
- B0.5 ~mol dm ⁻³ ~s ⁻¹
- C0.75 ~mol dm ⁻³ ~s ⁻¹
- D1.25 ~mol dm ⁻³ ~s ⁻¹
Correct answer
A. 0.25 ~mol dm ⁻³ ~s ⁻¹
Step-by-step solution
aligned Rate & = k [ A ][ B ]^2 & =6.25 ~mol ⁻² dm ^6 ~s ⁻¹ 1 ~mol dm ⁻³ & 0.2 ~mol dm ⁻³ 0.2 ~mol dm ⁻³ & =0.25 ~mol dm ⁻³ ~s ⁻¹ aligned
