Preferred Label : rate of change ratio;
IUPAC definition : The quotient of two rates where the quantities are of the same kind in the same system
for different components: \[\frac{{d}Q_{1}/{d}t}{{d}Q_{2}/{d}t}\] For finite time
intervals, mean rate of change ratio is: \[\frac{Δ Q_{1}/Δ t}{Δ Q_{2}/Δ t} \frac{Δ
Q_{1}}{Δ Q_{2}}\ Δ t\] Rate of change ratio has the dimension one. The denominator
is often called the reference quantity. Examples are: mass rate ratio, (dm1/dt)/(dm2/dt);
amount of substance rate ratio, (dn1/dt)/(dn2/dt).;
