Question

For each reaction order: identify the proper units for the rate constant; k. Not all of the choices will be used: Zero order First order Second order Third order M . $ M" Answcr Bank M

Answer 1

The units for the rate constant, k, vary depending on the overall order of the reaction, such as zeroth, first, second, or third order.

Step-by-step explanation:

The units for the rate constant, k, vary depending on the overall order of the reaction. For a zeroth-order reaction, the rate constant must have the same units as the reaction rate, typically moles. For a first-order reaction, the rate constant has units of reciprocal seconds (s¯¹) to have units of moles per liter per second for the reaction rate. For a second-order reaction, the unit of the rate constant is typically L mol-¹ s-¹. And for a third-order reaction, the unit of the rate constant is typically L² mol-2 s-¹.
