In a zero-order reaction, the rate of reaction is independent of the concentration of the reactants. What is the unit of the rate constant (k) for a zero-order reaction? (2023)
Step 1: Understand that in a zero-order reaction, the rate of reaction does not change with the concentration of reactants.
Step 2: Recall that the rate of a reaction is expressed in terms of concentration change over time, typically in units of mol/L·s (moles per liter per second).
Step 3: Since the rate is constant in a zero-order reaction, the rate can be represented as k, the rate constant.
Step 4: Therefore, the unit of the rate constant (k) must match the unit of the rate, which is mol/L·s.
