Question

Cyclopentene decomposes at 528 K as shown in the following reaction: C5H8 (g) ⇒C5H6 (g) + H2 (g)

Time (s) [C5H8] (mol L-1 )
0 0.02
20 0.0189
50 0.0173
100 0.0149
200 0.0112
300 0.0084
400 0.0063
500 0.0047
700 0.0027
1000 0.0011
Find the reaction order

Answer 1

rate=k×[C5H8]^n

k is the rate const.

when the rate is calculated using a few of the above data, (rate=change in concentration/time period) it can be observed that the rate is constant

therefore order of the reaction is 0
