Consider the reaction, `2A + B to` Products
When concentrations of B alone was doubled, the half-life did not charge. When the concentrations of A alone was doubled, the rate increased by two times. The unit of rate constant for this reaction is

Options

A. `S^(-1)`
B. `L mol^(-1) S^(-1)`
C. no unit
D. `mol^(-1) s^(-1)`

Answer

B

Explanation

In the reaction `2A+B rarr` products when concnetration of B is doubled the half life did not change for first order reaction when `(t_(1//2)=0.693//k)` when concentration of A is doubled the reaction rate is doubled rate constant for a second order reaction are `L mol^(-1)s^(-1)`
