Reaction rates are conventionally reported in which units?
A.mol L^-1 s^-1
B.s^-1 alone
C.L mol^-1
D.mol s^-1 alone
Explanation
Core Concept
Rate tracks how concentration changes per unit time, so its natural units are molarity, meaning mol per liter, per second. Whether written as M*s^-1 or mol L^-1 s^-1, the meaning is identical. These units serve the appearance of products and, with a minus sign attached, the disappearance of reactants alike. Stoichiometric ratios connect the various species' rates within one reaction.
Correct Answer
Amol L^-1 s^-1
