Total Attempts: 8
Accuracy Rate: 37.5%
Step-by-Step Solution
For a zero-order reaction, the rate of reaction is independent of the concentration of reactants. Therefore, Rate = $k[A]^0 = k$. The unit of rate is concentration per unit time ($mol\cdot L^{-1}\cdot s^{-1}$), which directly gives the unit of the rate constant $k$.
