What you learn in Theory:
• The rate of the reaction is proportional to the first power of the concentration of the reactant. • If we plot ln[R] against t we get a straight line with slope = –k and intercept equal to ln[R]0.
What you learn in Practice:
All radioactive decay reactions are first order reactions.
