The temperature at which the average speed of perfect gas molecules is double than at `17^(@)C` is

Options

A. `mol L^(-1) min^(-1)`
B. `L^(2) mol^(-2) min^(-1)`
C. `L mol^(-1) min^(-1)`
D. `min^(-1)`

Answer

B

Explanation

`k = ["conc"]^(1-n)min^(-1)`
For third order reaction `= [mol L^(-1)]^(1-3)min^(-1)`
`= L^(2) mol^(-2) min^(-2)`
