Secondly, it says that $N_o$ is the original level of C-14 and $N_f$ is the measured value. But how can you calculate how much has decayed if you don't know how much was there in the first place? So consider the following reaction: $$\mathrm \longrightarrow \mathrm$$ The rate can be expressed as the rate of change in the reactant concentration with a change in time such that $$\mathrm = -\dfrac$$ This simply means that [A] is being (i.e.
