Question

For a 1st order reaction the unit of rate constant is

A

$\({mol\, L^{-1}\, s^{-1}}$ )

B

$\({mol^{-1} \,L\, s^{-1}}$ )

C

$\({mol \, L \, s^{-1}}$ )

D

$\({s^{-1}}$ )

Answer

${s^{-1}}$

Explanation

Solution

For a first order reaction, Rate = $\(k[A]$ ) $\({ mol \, L^{-1} \, s^{-1} } = k ({mol \, L^{-1}})$ ) $\(k = {s^{-1}}$ )
