Expert Answer

Step 1

Cyclobutane, C4H8, decomposes when heated to ethylene, C2H4.

The reaction is first order.

 

Step 2

In an experiment,

the initial concentration of cyclobutane was = 0.00150 M

After heating at 450°C for time (t) = 455 seconds

final concentration of cyclobutane was reduced = 0.00119 M

Let us first calculate the value of rate constant (k) for a first-order reaction

formula,

ln[final concentration] = ln[initial concentration] - rate constant x time

or,

ln(0.001...
