Write the unit of the rate constant for the following reactions:
$1.$ Zero order
$2.$ Second order
$1.$ Zero order
$2.$ Second order
(N/A) The general formula for the unit of the rate constant $(k)$ for a reaction of order $(n)$ is given by: $(mol \ L^{-1})^{1-n} \ s^{-1}$.
$1.$ For a zero-order reaction $(n = 0)$:
Unit $= (mol \ L^{-1})^{1-0} \ s^{-1} = mol \ L^{-1} \ s^{-1}$.
$2.$ For a second-order reaction $(n = 2)$:
Unit $= (mol \ L^{-1})^{1-2} \ s^{-1} = (mol \ L^{-1})^{-1} \ s^{-1} = L \ mol^{-1} \ s^{-1}$.
$1.$ For a zero-order reaction $(n = 0)$:
Unit $= (mol \ L^{-1})^{1-0} \ s^{-1} = mol \ L^{-1} \ s^{-1}$.
$2.$ For a second-order reaction $(n = 2)$:
Unit $= (mol \ L^{-1})^{1-2} \ s^{-1} = (mol \ L^{-1})^{-1} \ s^{-1} = L \ mol^{-1} \ s^{-1}$.
