Question

Write the units of velocity and velocity constant for zero order reaction.

Hint:

The unit of a rate constant depends on the reaction order: for a zero-order reaction, it is \( \text{mol L}^{-1} \text{s}^{-1} \).

Answer 1

Step 1: For a zero-order reaction, the rate equation is: \[ \text{Rate} = k [A]^0 \] Step 2: The unit of velocity (rate of reaction) is: \[ \text{mol L}^{-1} \text{s}^{-1} \] Step 3: The unit of rate constant for a zero-order reaction is: \[ \text{mol L}^{-1} \text{s}^{-1} \]
