Problem

In a certain elementary reaction at 350 K, molecules collide at a rate of

1.0\times10^{9}

collisions per second. The Maxwell–Boltzmann distribution indicates that

8\%

of these collisions have energies equal to or greater than the activation energy. If only

25\%

of the energetic collisions possess the correct orientation for bond rearrangement, approximately how many successful collisions occur each second? (a)

3.3\times10^{8}

(b)

8.0\times10^{7}

(c)

2.0\times10^{7}

(d)

2.0\times10^{8}
