In the Radioactive Decay equation: -dN/dt=kN=kN(naught)e^-kt (pg. 64 in the course reader)
Why is there a k? and what does it represent?

Re: Radioactive Decay
Remember in class I discussed it is a rate constant called the decay constant. Since radioactive decay is 1st order one can write:
rate = kN where N is the number of radioactive nuclei (atoms)
As discussed, in chemistry for a 1st order chemical reaction one has:
rate = k[R]
rate = kN where N is the number of radioactive nuclei (atoms)
As discussed, in chemistry for a 1st order chemical reaction one has:
rate = k[R]
