For the reaction A + B product, rate law equation is, rate = k [ A ]^2[ ~B ] . If rate of reaction is 0.22 ~mol ~L ⁻¹ ~s ⁻¹ , calculate rate constant. ([ A ]=1 ~mol ~L ⁻¹,[ ~B ]=0.25 ~mol ~L ⁻¹ )
Options
- A0.44 ~mol ⁻² ~L ^2 ~s ⁻¹
- B0.88 ~mol ⁻² ~L ^2 ~s ⁻¹
- C1.136 ~mol ⁻² ~L ^2 ~s ⁻¹
- D3.52 ~mol ⁻² ~L ^2 ~s ⁻¹
Correct answer
B. 0.88 ~mol ⁻² ~L ^2 ~s ⁻¹
Step-by-step solution
aligned & Rate = k [ A ]^2[ ~B ] & 0.22 ~mol ~L ⁻¹ ~s ⁻¹= k (1 ~mol ~L ⁻¹ )^2 0.25 ~mol ~L ⁻¹ & k =0.88 ~mol ⁻² ~L ^2 ~s ⁻¹ aligned
