We’re being asked to **plot [C _{5}H_{6}] versus time**.

An **instantaneous reaction rate** is the rate at a particular moment in the reaction and is usually determined graphically and can be calculated as:

$\overline{){\mathbf{r}}{\mathbf{a}}{\mathbf{t}}{\mathbf{e}}{\mathbf{=}}\frac{\mathbf{\u2206}\left[\right]}{\mathbf{\u2206}\mathbf{t}}}$

Δ[ ] = change in concentration

Δt = change in time

Cyclopentadiene (C_{5}H_{6}) reacts with itself to form dicyclopentadiene (C_{10}H_{12}). A 0.0400 M solution of C_{5}H_{6} was monitored as a function of time as the reaction 2C_{5}H_{6} C_{10}H_{12} proceeded. The following data were collected:

Time (s) | [C_{5}H_{6}] (M) |

0.0 | 0.0400 |

50.0 | 0.0300 |

100.0 | 0.0240 |

150.0 | 0.0200 |

200.0 | 0.0174 |
