Units

[Parth Mungra]

What are the units for rate? Also, what are the units for the n or m values in the differential rate law?

[Patrick Cai 1L]

The units of the rate law vary with the order of the reaction, with the units of the general differential rate law given as moles/second ([change in concentration]/[change in time]).

[Albert Duong 4C]

Rate is typically in mol*L^-1*s*-1 or M/s where M is molarity.

[Vanadium Wang 4H]

The rate of a reaction is measured in terms of how fast the concentration of one of the reactants is falling. Its units are mol*L^-1*s^-1

The exponents m and n are called partial orders of the reaction which depend on the reaction mechanism and can be determined experimentally.

[megan blatt 2B]

Like the previous comment said, the rate is in mol*L^-1*s^-1 or M*s-1. The units of the rate constant changes with the order of the overall reaction to ensure that the rate always ends up with the units previously mentioned.

[Nina Do 4L]

As everyone stated above, it will be M/L per second and as you increase to each order, you're constantly dividing by 1/M so for zero order, the units will be Moles per second. s^-1
1st order will be per second or s^-1M^-1
and so forth

[Nada AbouHaiba 1I]

the m and n powers do not have units, they are just experimentally determined values
