WebSo the units of k for a second order reaction are one over molar, molar-seconds. so these are the three most common molecularities that you might see in a chemistry class. And sometimes, you have reactions that aren't zeroth, first, or second order, and whenever that happens, you can always use the rate law to find the units of the rate constant k. WebHome / All Definitions / Unit / Millihenry (mH) Unit Definition. Millihenry (mH) Unit Definition. The millihenry is a multiple of the unit henry (H) for inductance.The International System of Units (SI) defines the prefix milli (m) as a factor of 10-3 or 0.001. Per this definition, one millihenry is 10-3 henry. The millihenry is represented by the symbol mH.
