Question

A first-order reaction will yield a straight line when time is plotted on the x-axis and _______ is plotted on the y-axis.

Answer 1

In reaction kinetics, the equation that would best describe the relationship between time and concentration is,
                      dCA/dt = k or 
                          dCa = k(dt)
Then, we integrate both sides of the equation to yield.
                           Ca - Cao = kt
The first-order reaction will yield a straight line when time is plotted against the concentration.
