In a reaction, `2Ararr` Products the concentration of A decreases from `0.5` "mol" litre^(-1)` to `0.4` "mol" litre^(-1)` in `10` minutes. Calculate rate during this interval.

Options

A. 0.05 M `mi n^(-1)`
B. `0.005 M mi n^(-1)`
C. `0.5 M mi n^(-1)`
D. `5 M mi n^(-1)`

Explanation

Rate of reaction
`=1/2[(-d[A])/(dt)]=1/2[(0.5-0.4)/10]= mol L^(-1) mi n^(-1)`
`=0.005 mol L^(-1) mi n^(-1)`
