What are the units for the rate of the reaction?

The units for the rate of a reaction are moles per liter per unit of time.

Mol/(Liter*second); moles per liter per second

Typically the unit for rates is mol per liter per time unit.

Usually written as mol.L-1.s-1, which makes sense given that the rate can be represented by d[A]/dt, where [A] is in mol per liter over the time (dt)

Adding on, keep in mind that these units are the same for all rates regardless of order; because of this, the k constant of the reaction will have different units based on the reaction's order.

It is usually mol per L per unit of time, which is usually in seconds.

It would be moles per liter per time (in seconds)!

It's moles per liter per time in sec. However, the units for k will change depending on what order of reaction it is.
