Solution:
Cyclopentadiene (C5H6) reacts with itself to form dicyclopentadiene (C10H12). A 0.0400 M solution of C5H6 was monitored as a function of time as the reaction 2C5H6 C10H12 proceeded. The following data were collected:
Time (s)[C5H6] (M)
0.00.0400
50.00.0300
100.00.0240
150.00.0200
200.00.0174
Plot [C5H6] versus time.

Plot [C5H6] versus time.

Solution

We’re being asked to plot [C5H6] 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:

rate=  t

Δ[  ] = change in concentration
Δt = change in time
