Answer
Reaction c) has 4 possible factors: H-H, CL-CL,H-CL, CL-H. Only two of these are effective collisions.Reaction c) has the smallest orientation factor because it has 2 effective collisions out of 4. The orientation factor of reaction c) is 1/2 while reaction a) and b) have 1.
Work Step by Step
Firstly draw the reactants and products to see the possible collisions. Write the number of possible collisions. Next, see how many of the collisions are effective, and produce a product. Write the number of effective collisions. Finally divide the effective collision by possible collisions to get the orientation factor.
