Q. Consider following two reaction, $A \rightarrow product - \frac{d\lbrack A\rbrack}{dt} = k_{1}\lbrack A\rbrack^{0}$ $B \rightarrow product - \frac{d\lbrack B\rbrack}{dt} = k_{2}\lbrack B\rbrack^{0}$ $k_{1}and\ k_{2}$ are expressed in term of molarity $(mol\ L^{- 1})$ and time $(s^{- 1})$ as
A) $s^{- 1},M\ s^{- 1}L^{- 1}$
B) ${Ms}^{- 1},M\ s^{- 1}$
C) $s^{- 1},M^{- 1}s^{- 1}$
D) ${Ms}^{- 1},L\ s^{- 1}$
Explanation
(d)
A$\rightarrow product$
$- \frac{d\lbrack A\rbrack}{dt} = k_{1}\lbrack A\rbrack^{0}$
Units of $k_{1} = Ms^{- 1}$
B$\rightarrow product$
$- \frac{d\lbrack B\rbrack}{dt} = k_{2}\lbrack B\rbrack$
Units of $k_{2} = s^{- 1}$
