(1) alpha is your answer. The alpha particle is a Helium nucleus, with two protons and two neutrons. Therefore its larger than the positron or the neutron (because positrons have around the same mass as the proton, being its anti-particle). The beta particle is just the electron, in which the proton is way more massive than the electron.

We can have the relationship:

However,

Also, we assume m=1 which is the order of the reaction.

Thus, the relationship is simplified to,

r(t)/r0(t) = 2

r<span>(t)</span>=k<span>[<span>N2</span><span>O3</span>]</span>
