<u>Answer:</u> The concentration of ethene is 0.286 M
<u>Explanation:</u>
Rate law expression for first order kinetics is given by the equation:
where,
k = rate constant =
t = time taken for decay process = 15.0 s
= initial amount of the reactant = 0.500 M
[A] = amount left after decay process = ?
Putting values in above equation, we get:
The concentration of reactant consumed = (0.500 - 0.357) M = 0.143 M
For the given chemical reaction:
1 mole of butene produces 2 moles of ethene
So, concentration of ethene = (2 × 0.143) M = 0.286 M
Hence, the concentration of ethene is 0.286 M
Answer:
Kinetic energy would have to work ten times harder than potential energy.
