Preferred Label : change ratio of a quantity;
IUPAC definition : A term which may be expressed infinitesimally at time t by a ratio of differentials
dQ1(t)/dQ2(t) where the kind of quantities are the same but for different components
in the same system. In practice, the ratio for a finite interval is: \[\frac{Δ Q_{1}(t_{1};\,t_{2})}{Δ
Q_{2}(t_{1};t_{2})}\] Examples are: mass change ratio, dm1(t)/dm2(t); amount of substance
change ratio, dn1(t)/dn2(t).;
