The rate of the reaction, CH ₃ COOC ₂ H ₅+ NaOH CH ₃ COONa + C ₂ H ₅ OH is given by the equation, rate =k [ CH ₃ COOC ₂ H ₅ ][ NaOH ] . If concentration is expressed in mol ⁻¹ , the unit of k is
Options
- Amol L ⁻¹ ~s ⁻¹
- BL mol ⁻¹ ~s ⁻¹
- Cs ⁻¹
- Dmol ⁻² ~L ^2 ~S ⁻¹
Correct answer
B. L mol ⁻¹ ~s ⁻¹
Step-by-step solution
Given that, rate =k [ CH ₃ COOC ₂ H ₅ ][ NaOH ] That means the reaction is a second order aligned d x d t & =k[A]^2 conc time =k[ conc. ]^2 mol L ⁻¹ ~s & =k ~mol ~L ⁻¹ mol L^ -1 k & = L mol ⁻¹ ~s ⁻¹ aligned
