Answer 2

Ans: B) Time

Rate is a measure of change of a particular property over a certain time period. The property could be concentration, volume, mass etc.

Mathematically, if x denotes a certain property and t denotes the time then:

Rate = Δx/Δt = x2-x1/t2-t1

x1 and x2 are the initial and final values of the measured property measured at time t1 and t2 respectively.

Thus, rate is related to time.
