For this lab, the reaction system consists of two reactions, dimerization and dissociation:

* \$$2X \rightarrow X_2\$$, with rate coefficient \$$k_1\$$ = 50,000
* \$$X_2 \rightarrow 2X\$$, with rate coefficient \$$k_2\$$ = 0.2

Let:

* \$$X[t]\$$ be the count of the number of monomers \$$X\$$ at time \$$t\$$
* \$$X_2[t]\$$ be the count of the number of dimers \$$X_2\$$ at time \$$t\$$
